GT5, no question about it. Exclusive, a historically huge performer, and it's going to be absolutely massive.

Gran Turismo 5 FTW

GT5 won't get anywhere near MW2 by the time it releases. MW2 will likely get there before the prolific racer is even released!

Im still hopeful of it coming out before 2012

Maybe CODMW but depends when COD 7 comes out......

Well these are the 3 only games that have a shot... the most probable of the 3 is MW2. GTA5 is next and GT5... well I wouldent bet on the 10 million mark TBH, tough 8 million is likely At this point on I cant think of any other game that could hit the 10 million mark on the PS3, and even if a MW3 would come out in 2 years, it would be to late to leg it out to 10 million... tough who knows, right?

GT5 will easily do it, you only have to look at the history of GT to know this,

Gran Turismo 5.

3.5M First week, 1.5M second week, quote me on it.

FW:
800k Jp
1.2M US
1.5M EU
SW:
200k Jp
600k US
700k EU

and it'll have the best bundle and the best legs you've ever seen.

look at GT5p...3.68 almost Confirmed buyers FW/SW....the best Prologue in terms of sales, this is the most anticipated GT ever, with a 35M+ Userbase without piracy and with a much bigger market than before...the 1st AAA racing game on the console, highly acclaimed with different types of racing to appeal different regions ( NASCAR, SUPER GT, RALLY, etc.)
this is the biggest card sony has, d'you think that they'll let it pass when we know how much it means for them?
