The much anticipated Diablo III is scheduled to be out in Q1 of 2012 now, according to
Battle.net. The 2011 launch window has been disregarded, much to the chagrin of the millions of eager fans. Even though they have repeatedly said the game was due to launch "soon" this shouldn't come as a surprise for anything done by Kotick, or Blizzard. Their quality and polishing standards are second to none when it comes to their games.
We commonly use the term “soon” when referring to Blizzard releases, because we know that no matter how hard we’re working to reach a target, we’re not going to compromise and launch a game before it’s ready. - Mike Morhaime of Battle.net
