I'll go through every famous game scheduled for PS3 which we know something about and rate its chance of getting a million first week from 1 to 5:
Demon Souls - 1
EyePet - 1
God of War III - 4
Gran Turismo 5 - 5
Heavy Rain - 1
inFamous - 2
Killzone 2 - 4
Massive Action Game - 3
Ratchet and Clank Future 2 - 2
Uncharted 2 - 3
WarDevil - 3
Way of The Samurai - 2
White Knight Chronicles - 3
X-Edge - 1
Yakuza 3 - 2
Final Fantasy XIII - 5
Final Fantasy Versus XIII - 5
I think only 4 and 5 can count, so God of War III, Gran Turismo 5, Killzone 2, Final Fantasy XIII and Final Fantasy Versus XIII.
