As we announced a little while back, with the upcoming release of patch 2.0.1, your Diablo III launcher will be automatically updated to our new desktop app for Battle.net. You can upgrade now if you like, but if you haven't done so yourself by the time patch day rolls around, here’s a quick heads up about what you can expect.
When you start your Diablo III launcher for the first time after Patch 2.0.1 launches, you'll receive a quick tools update, and then you'll be prompted to begin the process of optimizing your Diablo III installation.

It could take a while—anywhere from 15 to 60 minutes, even on a monster machine—but it's an important part of prepping for Patch 2.0.1 and Reaper of Souls.
Next your Diablo III launcher will download the rest of the data you need—you'll see the usual red, yellow, and green data indicator during this process. How much data you'll need to download depends on how much background-downloading you've done already.
Once the Play button lights up, you can click it to enter the game and dive into the new Patch 2.0.1 content! Your launcher won't actually be updated to the desktop app Battle.net until the next time you start it up—so slay as many demons as you want, and then quit only when you've sated your bloodthirst.

The next time you launch Diablo III, you'll be greeted with a pop-up screen letting you know your launcher is about to be updated to Battle.net.

Click Start Installation to start the process.
It shouldn't take too long, but keep in mind you may need to click a Restart Now button at some point during the installation process.
When you see the Battle.net login prompt, enter your account information, and click Log In.
Once you see the screen below, you're done!
Click Play from the app's Diablo III screen to get back into the game at any time (you won’t have to log in again), or launch the game from your desktop as usual. For more information on Battle.net, check out the Battle.net web page and Support article.
Heads up for those who've already upgraded their launcher to Battle.net (or who plan to do so before Patch 2.0.1 launches):
On patch day, you will also have to go through a code-optimization process similar to what's outlined Step 1 above. Expect it to take 15 to 60 minutes or so, and keep in mind your computer might run a little slower than usual during the process.
That's it! Happy hunting!
You've fought bravely against the forces of the Burning Hells, banishing the Prime Evil and restoring Hope to the High Heavens. However, a new terror awaits. Soon, the sickening forces of Death will advance on the mortal realm of Sanctuary, ushering in a new age as Diablo® III: Reaper of Souls™ is unleashed upon the world.
The time has come for heroes to rise to a new challenge and prove their mastery of both the sword and the pen. So, crack open your stash of art supplies, nephalem, and get ready to get crafty!
To celebrate the upcoming launch of Reaper of Souls, Blizzard Entertainment and deviantART have joined forces to bring you a truly Legendary fan art contest. With over $11,000 worth of prizes and a two-night trip to Blizzard HQ in Irvine, CA up for grabs, we're calling all talented artisans from Caldeum to Kehjistan to take up their styluses in defense of the realm.
Your challenge, brave heroes, is to channel your arcane power and create an illustration depicting one or more central figures of the expansion getting ready for the coming conflict against the Angel of Death. These figures may include the six heroes of Sanctuary or even Malthael himself.







Your entries will have a chance to be seen not only by the millions of passionate Diablo players from around the globe, but also by the teams at both Blizzard and deviantART. In addition to scoring some truly epic prize packages that even the pickiest treasure goblin would be jealous of, the top 25 winners will also have their art displayed at Blizzard's headquarters in Irvine, California, with the top three winners hand-selected by Christian Lichtner— art director of Diablo III.
We've shared some of the tantalizing contest details below, but make sure to head on over to deviantART’s contest page for further information as well as the official rules and submission guidelines.
Best of luck to all artisans, and may the most devious designs win!

The Design a Legendary project is well underway. So far, we've selected the weapon type, weapon theme, and the vote for the item's Legendary power is nearly complete. The concepting phase has also concluded for the item's visual appearance, and we'll be able to share with you 3D models and low-rez screenshots of item in-game early next week!
But there's still one big thing left to decide: the item's name.When we originally started the Design a Legendary project, our goal was to host an official naming contest near the end of the design process. We even had super fancy legal Terms of Use all drawn up and ready for digital print.
Unfortunately, even the best laid plans of mice and CMs can go awry and, due to development deadlines, a full contest isn't in the cards at this point -- especially since we want to make sure that this Legendary is available with the release of Reaper of Souls (rather than needing to be patched in later). But have no fear! It's still very important to us that the name of this Mephisto-themed, one-handed sword to be chosen by you, our players, so we've come up with *cue trumpet flare* other plans.
Over the past week, we've scoured forum posts, blog comments, tweets, and more wherein players have suggested some amazing names for this particular Legendary. Of those names, our designers have chosen five which fit the tone and theme of the weapon. Those five player-submitted names are:
So, pick your favorite by using the voting options below, and be sure to spread the word. As with previous votes, whichever name gets the most votes globally wins!
After the poll has closed, we'll tabulate player votes from all our different Diablo III communities around the world to determine the winner and share the results next week. Don't delay, though—this poll will close Wednesday, January 29.
In preparation for death's imminent descent, your Diablo III game launcher will soon be upgraded to our new desktop app for Battle.net. You'll receive the update automatically with Patch 2.0.1, arriving in the weeks leading up to the March 25 release of Reaper of Souls.
