During a recent investors call, Blizzard have stated that they are ‘targeting’ a Q3 (late summer) release for a public Diablo 3 beta. As of yet there has been no confirmation of a release date for the title other than it should come out this year. Blizzard big-wig Michael Morhaime stated that Blizzard are”working hard to release the game this year”, but added it “will not compromise the quality of the game to hit a launch window”.
