Diablo 3 - Q2 Release, "You Will Die. We Promise."

A conference call on Activision's latest financial results, Blizzard's Mike Morhaime confirmed that Diablo 3 has been delayed into a Q2 release, according to IncGamers. The delay (previously "early" 2012) is a result of the recent changes, following beta testing. Here's a quote:

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.

In other news, the Diablo 3 site promises Nightmare difficulty will be plenty hard and offers a video featuring developers answering that question at Blizzcon.
