Will MGS4 numbers be > or < than GTA4 for PS3?

[EaglesEye379]

Bomb level: slowly reaching towards 1m
Decent level: BioShock, Mass Effect (1.8-2m)
My expected level: 2.5m
What Sony fanboys wish level: Gears of War (5m)
No f*ing way level: Halo 3, GTA4 (8m)

OT: No way its going to beat GTA4 on PS3 (with expected 5m sales)
