Dont say it then if you dont have proof, you have said it in minimum 2 threads. If you can find a source I will accept it but c'mon man.
And yes forza 4 will only most likely outsell gt5 in US, but that is why the OP posted.
i don't know maybe forza 4 will outsell gt5 in the u.s.a but it's not right to compare 2 games like that! i could say gt5 can outsell forza 1-3 with all that bundling forza 3 and 2 got but i know it's not right to compare forza with gran turismo because there at two completly seperate leages. Gt5 can sell 9 million without bundles and 10.5 million with bundles if you compare gt5 with halo it's fine if you compare uncharted sales with halo sales that just puts those ps3 owners start doing stupid things and start putting gran turismo in front of games like left 4 dead even though the 2 are not realated in anyway
btw i own both ps3 and xbox 360 and am not a fanboy i am not saying which one is a better game!
