Lylirra has confirmed that Blizzard is planning on increasing monster density in various Acts.
Wyatt Cheng went into a bit more detail on the topic of monster density.
Yup! Pretty much this.
We're spending time working on monster density in Acts I, II and IV because while optimal routes are inevitable, we want things to be close enough that options exist.
Currently we have a situation where a small number of specific runs are twice (or more) as effective as your average run. This margin is too large and overshadows other factors. Our goal is to make the monster density in Inferno close enough that factors such as your skill choices and gear level start to become more relevant. Let's suppose you were trying to optimize XP/hour. What if a cookie-cutter Archon build on MP1 had one optimal run, but an SNS Wizard on MP3 had a different optimal run? Different areas also have different monsters with different abilities. Some classes have an easier time dealing with particular monster types, this can cause the “optimal run” to shift as well. If we get the overall densities closer, these other factors will start to become more relevant rather than the current situation where the raw monster density of a run dominates all other factors.
When things are close enough, you may try a run that is a little less XP/hour if it means increased Demonic Essences. Maybe you just really enjoy the art of the Act I jail. Maybe you just want some variety and haven't been to an area in a while. Maybe you want to do a full play through in co-op with a friend. It’s a matter of degree -- these aren't tradeoffs most players would make when the run results in a 50% loss in efficiency, but if the difference is 5-15% then these other factors come into consideration.
So, like Lylirra said, our goal is to avoid creating a new “most optional” run, and instead provide players with an environment that allows them to choose from multiple different options.
Travis Day dropped more information about Monster Density and other planned features for patch 1.0.8. These include things such as crafting more than one item at once and Auction House Tooltip comparisons.
Ok I've finally caught up on all the responses in every location I could find them! This blog was written a while ago and between when I wrote it and when we released it a lot more relevant ideas came up so I want to mention a couple of them. I'm going to keep this short and to the point so I can get back to working on actually improving the game instead of talking about it. ;)
Below is a list of things that players can hopefully expect to see as soon as patch 1.0.8.
Mob densityActs 1, 2, and 4 will be receiving some adjustments in Inferno difficulty games. We want to try to make all of the acts as comparable as possible so that players don't feel they always have to farm the same areas of the game repeatedly, diversity is the spice of life.
Multi Craft
We want to make it easier to craft lots of items, so we plan on giving players the ability to specify how many of an item they want to craft and then to make that many. Want to make 20 Archon Shoulders of Dexterity? Cool, push the button and watch it go.
AH tooltip compareEver wish you could compare the item you are thinking about buying with the item you are wearing? You want it, we want it, and we hope to have it in game soon.
In addition to the changes we introduce in 1.0.8 we also have longer term plans to address issues that need more attention. I mentioned a lot of these long term plans in the blog and outlined some of our philosophies that will drive the itemization of Diablo forward. One of those ideas that I saw mentioned repeatedly in response to the blog is the fact that class specific items can roll non class appropriate primary stats, we have plans to change this down the road. While random really is at the core of Diablo in so many ways this is certainly one of the areas where it has no potential to benefit players. Wizards don't use Strength, Demon Hunters don't use Intelligence so let's just remove those as potential random attributes on Orbs and Quivers respectively.
Itemization changes planned for after patch 1.0.8?
For right now (since 1.0.8 is still being developed), we aren't going to have a lot of additional details to share about what's included in the patch. As development continues, though, we'll be sure to share more information -- most likely in the form of a patch preview blog like we've done in the past, as well as just talking about stuff in here in the forums.
The distinction I was making with my previous post is that most of the changes Travis' discussed in his blog aren't coming with 1.0.8, but are instead being planned for sometime after 1.0.8 ships.
(PS - HI WYATT. HI TRAVIS.)
Sorry but it is hard to follow. What features or changes are not included in patch 1.0.8?
No worries. :) The only changes we've confirmed to be working on for 1.0.8 so far are Identify All, a new multi-craft option, monster density adjustments, and AH comparison tooltips. Travis sums everthing up quite nicely here: http://us.battle.net/d3/en/forum/topic/8087879561?page=4#76
The other changes in Travis' blog are being discussed for after 1.0.8.
The item hunt is core to the Diablo experience and we're determined to make it even better in Diablo III. We've made several adjustments to the item game since launch with this goal in mind, but today I wanted to talk about a few of the underlying philosophies that are driving future changes to itemization.

Rarity = Power
One of the big things we want to focus on is making sure items that feel like they are rare and powerful are actually powerful . . . instead of just rare. The first and most obvious place for improvement here is Legendaries.
By design, Legendary items are going to drop far less often than Rare items, and we want that rarity to be reflected in their power. When a Legendary drops, the question that goes through a player's mind should never be "is this a good item?" It should be "how awesome is it?" For example, if you are playing a Demon Hunter wielding a Rare crossbow and a Legendary crossbow drops, we want your reaction to be "Holy crap, YES!" not "*sigh* another Hellrack." It's a problem if players don't want to bother identifying their Legendaries, let alone pick them up. We want to change this.
Legendary Stat Ranges:
Lots of factors go into making an item good, and one of those factors is how high the stats on the item can roll. When the game first launched, an item's potential stats were largely indicated by its item level. This made it so you'd know in advance whether or not an item was worth the trouble of identifying. In 1.0.5, we made it so that the stat ranges for affixes were based on the level of the monster or container that dropped the item rather than the item's level, which created the possibility of more items rolling competitive values.
We’d like to continue with this line of reasoning and use it to make Legendaries more powerful. In the future, we plan to allow Legendary items to also roll their base stats (weapon DPS and armor value) at the level of the monster that dropped them. So, for example, if you found a Heart of Iron from a level 63 monster, its base armor would be increased to that of Archon Armor and its stat ranges would roll at level 63. This gives us the opportunity to broaden the range of Legendary items, providing players with more diversity. Love Leoric's Signet, but hate wearing a level 17 ring? Me too. Instead of farming Act II Normal to find a Leoric's Signet, let's go farm Inferno and get a level 63 version of the ring!
(Everything we're suggesting for Legendaries also applies to Sets, too, by the way.)
Increased Item Diversity:
Item diversity is a topic that comes up a lot. Right now when people are talking about the best items in the game or looking for ways to improve their power they gravitate towards items with Critical Chance, Critical Damage, and Attack Speed. While these stats are great for boosting your damage they aren’t necessarily interesting or what we like to call "game changing."
We want players to feel like entire new builds can open up if they get their hand on the right items. Glimmers of this idea are already in the game with The Three Hundredth Spear and Thing of the Deep. The plan is to embrace the idea and push them to more extremes. Potential future Legendary item ideas include a Voodoo Mask that increases pet damage, a Barbarian set that makes Call of the Ancients last until they die (after we give them full pet survivability), a Wizard Orb that allowed for two Hydras to be active at once, or the "Ethereal" boots idea I posted here. While these specific ideas may not make it into the game, they are good examples of the kinds of game changing effects we want to introduce to items. It will take time, but our goal is to try to provide players with compelling alternatives to trifecta items when talking about what items they want to acquire.

Between Paragon levels, Nephalem Valor stacks, and all the other assorted buffs and bonuses, it's possible to find a tremendous amount of Rare items during any given play session. But the quality of these Rare items just isn't where it needs to be, so even though players see a lot of them, they no longer feel special. When you identify hundreds of Rares and only a small percentage are worth equipping or selling, those items become a burden rather than something to get excited about. "Great. Now I have to identify them all, read their stats, and I’m probably going to salvage all of them." I feel your pain.
We want to make it fun and rewarding to hunt down new items through play, and really instill the feeling that your next awesome item could come from anywhere, and is just around the corner. We need to get rid of some of the clutter first, so we plan to reduce the frequency at which Rare items drop down the road.
Before anyone panics and posts an angry comment in the forums, this doesn't mean we want players to earn even fewer good items. It just means we don't feel it's necessary to present the player with hundreds of bad Rares for every one that they might want. As an example, suppose items currently roll between 1-100 Intelligence. Now, imagine that we dropped 25% as many items, but the Intelligence range was instead somewhere around 75-100. In the end, you'd find fewer items, but more of the items you find would be worth equipping. That's our goal.
(On the topic of identifying hundreds of Rares, it's worth adding that while most of this blog is about overall item philosophy and our goals down the road, one of the short-term changes we're making is adding an "Identify All" option, which should be coming in 1.0.8.)

We frequently discuss the Diablo economy, as we want players to feel that gold is a valuable commodity, useful in ways beyond just the auction house. We don't want out of control inflation, but we also don’t think that taxing players is the proper approach. Ultimately, we want to provide players with things that they are excited to spend their hard-earned gold on.
The most concrete example of how we're supporting this philosophy would be the crafting recipes we introduced in patch 1.0.7. While they aren’t meant to be the silver bullet for all economic concerns, they provide more avenues for people to spend their gold to receive something they can be happy about—in this case, potential upgrades for their character or alts.



For more insight into Bind on Account items, check out Wyatt's 1.0.7 preview here.
Other avenues we want to explore include providing players with vanity options or potential ways to differentiate themselves from their friends or other characters (i.e. character customization options in terms of gear). We are also exploring ways to make crafting more exciting by adding not just more ways to make appealing items, but also introducing ways to modify existing items.

The auction house is a new addition to the Diablo franchise. And, while it serves many purposes for our players and helps to keep the economy fluid, some would argue that it has done more harm to the game than good. There is value to be had in providing players a way to freely exchange unwanted items for gold, or giving Demon Hunters an easy means to sell unwanted rubies in order to purchase emeralds, but the question has to be asked: is what the auction house provides worth what it took away from some players?
If the "right" way for some people to play the game changes from killing monsters to camping the auction house, is the game better off for it? Ultimately we don't think it is, but we also don't want to take something away that has become such an enjoyable part of the game for others. So, the question instead becomes: how can we refocus the end game away from farming the auction house back to farming monsters? It's a complicated issue, but one we are committed to addressing.
The first solution always presented when we discuss this problem is "Why don’t you just get rid of the auction house?" and while completely removing the feature would in fact fix the problem it created, it would also create a void that the auction house was originally designed to address. For example, we don't want players to feel like the only way to trade with other people is by sitting in chat and spamming "WTS [item link]" and "WTB [awesome item]" all day. This is definitely not ideal.
There are a number of ideas for how to address this long term that don't include removing the auction house outright, and most of the ideas are centered around giving players more ways to find items they are excited about:
The list goes on and, as with all design, nothing is ever final. This is just a snapshot of what we're working on currently with regard to itemization, and we hope to provide more specifics as we get closer to implementing these changes into the live game. In the meantime, we'd love to hear what you think about our approach, since much of what's cited above has been inspired by your feedback.

Rules & How to Enter:
Back in 2011, plans were made to create the ultimate Diablo III website centered around the real-money auction house, and so D3RMT was born (for those who are not aware, D3RMT stands for Diablo III Real-Money Trade.) As time went on, we found that we did not want to be just a website about the auction house, but rather be the one-stop place for news, guides, community, and more. It only makes sense that we update ourselves to a more appropriate name, one that conveys a message of who we truly are. After hours of thinking and names being tossed around, we finally came up with DiabloHub. So update your bookmarks, tell your friends, and continue having fun!
With the name change comes an increased focus on our guides and events sections.
Blizzard has been hinting towards a console release of Diablo 3 for quite some time. Back in December, they mentioned that they already had a version running on unspecified consoles. However, the official announcement of the PlayStation 3 & 4 release has provoked a negative reaction among players. This announcement came as a shock to many, and the idea that Diablo 3 has been “dumbed down” for consoles is being discussed on forums everywhere. A common concern amongst members of these forums is that Blizzard has sold out since their merge with Activision, and that releasing Diablo 3 on consoles is not what the old Blizzard would do. If you take a moment and look at the big picture, the games in the Diablo series, among other ARPGs, have always been a good fit for consoles. Blizzard Entertainment actually started as a console developer with titles such as Lost Vikings and Blackthorne. The first Diablo title was a huge hit on the original PlayStation when it was released back in 1998, and after Diablo 2 was released the developers planned on making a Diablo Junior game for the Game Boy Advance. The project has long been scrapped, but what we do know about it is that Blizzard wanted to release three variations of the game, each one featuring a different hero. The ability to trade across game versions (similar to the Pokémon series) was to be a major focal point of the game. The only footage available of Diablo Junior is from a very early alpha version of the game.
The idea that Diablo 3 will suffer because of a console port is a bit of a stretch to make. Starcraft being ported to the Nintendo 64 didn't ruin it, did it? Even full blown MMORPGs such as Everquest and Final Fantasy 11 have been released on consoles without negatively affecting the PC experience. Blizzard's official stance on the matter is that the console port never impacted development, and that there is an entirely separate team working on it.
