I think that the 4th yet to be revealed game for Blizzard will be a new IP for the consoles. It just makes sense to me with the state of the pc gaming industry and the explosion of the console market for them to try to break into it. As to the people who are up in arms over the graphics and design of Diablo 3 are you crazy? The game to me looks amazing. While I will still have to bite teh bullet and build a new gaming machine to play this it's nice to know I wont have to blow a ton of money on upgrades to experience the title at it's best. Same goes for Starcraft 2. Blizzard realizes part of there games staying power is that they run on a diverse set of specs. People know that when they buy a Blizzard title that it will more then likely play pretty well on a machine that is two or 3 years old. That's why they take a long time for there games great optimization.
