Any ideas what this will be? I can't tell now that GTA IV is off the table for the time being.

The big games for the PS3 this year, as far as I know, are as follows:

Heavenly Sword
Lair
Ratchet and Clank Tools of Destruction
Madden 08

Am I missing any? That's all I can think of off the top of my head. Of these, the first three are all made by Sony, and Madden is unlikely to sell a million, both because it is the inferior version and its sales will come entirely from America and its 1.74 million user base. Speak up if you have an idea!

I say Madden, buy it will take some time to do it.

nope. I don't think there is one right now that has a firm release date.

URT3
Haze
Need for Speed pro street
Assasins Creed
COD4

Should do well in NA ans Europe, NFS is the likely one cars sale everywhere.

Guitar Hero or Rock Band FTW.... easily

EDIT: Assassin's Creed might have a chance to challenge them.

Sadly Madden :(

taht's the problem I don't see witch one would....especialy due to the awarness of people abouth those games... I'm not saying they are good or not... but it's the same question about ME or BS on XB they might be good we still don't know how they will do... I would have said madden... the problem.... well you pointed it out already

I'm gonna guess Haze at this point but it's really a tossup which of the holiday hits could do it, if any of them.

PS: It won't be Madden.

The million seller list is:
motorstorm
resistance:fall of man

Cod4 is the only third party I see selling 1 million as well as URT3.

Asfor first party:
Heavely sword
Uncharted:drake's fortune
HSG5 tops the list at least for this year.
