With the recent announcement of the Diablo3 beta, we all thought the game would be on track for a holiday 2011 release, but a current announcement has informed us of a new release window of early 2012. You can read the news on blizzards website here. On the bright side, they did announce they'd be able to add more people to the beta as time progresses seeing as it's going to go a few months longer than expected.
In related blizzard news, if you're interested in Growing an amazing beard feel free to do that in anticipation of Diablo3's release. I haven't decided if i'm completely on beard yet but I've definitely got the manly 5oclock shadow going on atm.
