You can see the Blizzard segment about 38 seconds into the video here:
"Blizzard has been in talks with Microsoft over the next Xbox. Rob Pardo confirmed at GDC that the new system is already in development. Pardo also mentioned why World of Warcraft hasn't come to the console: the current hardware just isn't designed for it."
Obviously, WoW has been Blizzard's bread 'n butter for a while now, but here's hoping that this means we'll possibly get to see Diablo 3 released on consoles as well.
So how many of you would be inclined to purchase the next Xbox if you knew some of Blizzard's future games were going to be on it? Would it influence your decision? Naturally, this is assuming the games turn out much better than the Diablo port for the original Sony Playstation did. ;)
