"It’s official. During the Activision Blizzard Q1 2011 Financial Results conference call held today at 1:30pm PDT (4:30pm EST), Blizzard Entertainment CEO Mike Morhaime officially announced Diablo III beta testing will commence this upcoming Q3 2011. It was not specified if it’s a fiscal Q3, or otherwise. One could extrapolate Diablo III Beta might start in early July, after the Diablo II anniversary, which coincides with the Diablo III official announcement held in Paris at the 2008 Blizzard Worldwide Invitationals. Here is the quote from Blizzard Entertainment CEO Mike Morhaime during today’s Activision Blizzard Q1 2011 Financial Results conference call:

Morhaime: “On the Diablo III front, I’m pleased to report that we began internal company live testing last week. The game is looking great, and we are currently targeting a Q3 Launch for external beta testing. The development team is working hard to try and launch Diablo III this year. But I want to be clear that we do not have an official release date or window yet. As always we won’t compromise the quality of the game in order to hit a window.”
