It's called "gears of war" and is expected to be as lucrative a franchise for the x-box as Halo was. I know developers who work on both x-box and ps3 titles and there's really no contest between the two consoles. The game developers prefer the x-box.
Nintendo's graphics are several generations old, but their controllers -- how the gamer interacts with the game -- are definitely the wave of the future.
XBOX is the big winner this season.
WII is a big runner up
PS3 They sold out a limited number of sets to a few die hard fanboys but they'll have a really hard time moving enough units to catch up to the x-box or even the wii.
