We'll have articles in the coming days providing all the details on the upcoming patch, but we wanted to give you a sneak peek at some major features currently in development:

Defensive Skill Changes
In our eternal quest to promote build diversity, we'll be making changes to defensive skills across the board while simultaneously reducing incoming damage from mosters. The net result is a survivability buff for playersand an increase in build options as defensive abilities become less "mandatory."
New Event: Infernal Machine
The Infernal Machine is a device that will allow level-60 players to battle "uber" versions of some of Sanctuary's most nefarious bosses. While the rewards for defeating these bosses will be great, some assembly is required.
New System: Monster Power
Similar to the "Players 8" command in Diablo II, the Monster Power system is designed to give players more control over how challenging enemies are in each difficulty.

This and more is coming in Patch 1.0.5! Stay tuned for all the gory details.

it was a lot more difficult and the AH didn't really have that many items back then.
and I guess you had low DPS back then.
After thinking about this a while, my initial excitement has worn off. I did like /players 8 and Uber Diablo functionality in Diablo 2, but this isn't Diablo 2. It would be really nice to have additional original ideas. It just feels like it's becoming more and more like Diablo 2.5 and less like a new game entirely. The player base may just want Diablo 2 again, but that doesn't mean Blizzard should give it to them/us.
I hope they put a substantial different spin on these concepts with Monster Power and Infernal Machine unlike Paragon Levels which is a welcome, but very uninspired concept.
I'm still pretty excited for the patch. Sounds like the patch will drop next week or the week after.
