I personally think Modern Warfare 2 will be the only 10 million seller for the PS3, I don't think Gran turismo 5 will be a ten million seller at'll unless they bundle the hell outta it. Same goes for GTA next, if its a huge improvement from gta4

Hard choices, I think it will be GT5, but MW2 may beat it. Personally I dont think it will reach that high, but it may. I think GTA and GT5 both will sell that many though.

Modern Warfare 2. It's already over 7 million, and it's going to sell a bunch of copies leading up to this year's holiday season. And since I'm expecting Treyarch's next Call of Duty to disappoint again (although Viet Cong Zombies will be awesome), Modern Warfare 2 should have a strong holiday season.

Grand Theft Auto V (or whatever it may be called) has the potential to be a 10 million seller on the PS3 (and the 360), but it needs to offer a much better online system, as well as get back to sandbox roots. Make tons of crazy shit to do, and the series will have crazy sales once again.

Well i am pretty confident that GT5 will sell 10mil, but whether it can get there faster than MW2 is hard to say. I suppose MW2 will probably be the first, but i think GT5 will sell more lifetime, GTA i'm not so sure about, i really think the GTA name has been hurt by GTA 4

Probably MW2

If Gran Turismo 5 does eventually go on to sell 10 million (Which all signs point that it will) then it will do so over a considerably long period of time. Gran Turismo is a franchise that sells on legs. So the question is pretty much whether or not Modern Warfare 2 is going to hit 10 million. If it doesn't then Gran Turismo 5 will probably be the only other game likely to.

Gran Turismo 5 + Prologue will sell 10 million total since Prologue is part of GT5.

i dont think any sony exclusive will sell 10 million .they havnt got close yet modern warfare 2 is the only one i think GT5 will sell around 5-6 million

I know I'm going to regret this, but... why?

Lifetime sales I'm pretty sure that GT5 might reach it, MW2 not really, 3 millions more is a lot especially when its declining every month and the 360 version doesn't even hit top 10 anymore. Also there will be Cod7 or w/e its called in 8 months, after that the game wont even sell 1 million copies until the next one arrives.
