After some leaked info that Blizzard was hiring a console division for their new RPG game Blizzard has all but announced Diablo 3 for consoles. Prima shares the tweets here; http://ht.ly/8oNTq
Looks like it was updated with some obtuse language. "It was a confirmation that we were actively looking into the possibility of a console release" Thanks, Blizzard.
Looks like they *could* make it just like the PC version. There are only 4 or 5 abilities (I haven't looked at a screenshot recently) on the bar, so those could be A/B/X/Y. There are other dungeon crawlers for the consoles... Dungeon Hunters on the PS3 and there's some xbox live arcade game... Torchlight I think. It *is* possible.
