According to Diablo III lead designer Josh Mosqueira, Blizzard "is very, very serious about bringing the Diablo III experience to the console," and the developer is currently recruiting a team to handle the initiative. "We're looking for programmers, designers, artists who think their dream job would be to bring Diablo to the console. Trust me, it is a dream job. All I can say is it's going to be awesome. Stay tuned."
It'll be interesting to see what an adaptation for the Xbox 360 and PlayStation 3 will be like, especially since the PlayStation 2 attempt to bring Diablo to consoles was a disaster.
Diablo III has no release date yet on PC, but a beta will be launched sometime in the coming weeks.
