I'd say it depends on how the game is, if the game is a big step up from the original and everyone talk about it, it will sell systems. If its got some mediocre reviews then it will not sell systems obviously.
I think Halo2 sold many xbox's because of its online capabilities, it was the best online game at the time.
Can't wait for gears2, I hope it doesn't flop.
My favorite games for this gen:
1. Gears of War 2. MGS4 3. Killzone 2 4. Halo 3(Underated by many) 5. Mass Effect
