It's the first God of War title to grace the PS3.
A lot of hardcore GOW fans will buy it to play in 720p, 60fps, and the trophies.
A lot of people who never played GOW 1 and 2 will buy it so they can follow the story when GOW 3 comes out in March.
It sort of reminds me of GT5 Prologue. It's really just to get people hyped up for the main release.
I think 1 million sales for GOWC, maybe 1.5 million. We should also note that it's releasing the same day as MW2.
