The site reports on Blizzard's recent investors call, during which Mike Morhaime stated the obvious before alluding to the launch window. "Given the popularity of the action RPG genre, and the keen interest in Diablo III, we expect this launch to be a big opportunity for Blizzard. We can also confirm that we are targeting a Q2 launch for Diablo III. We expect to announce more details about the release schedule in the coming weeks," he said.
But hey, at least he didn't say "when it's ready."
