GTA4 will sell 7 million on PS3, 10 million on 360 (thats right, it'll beat halo 3)

and MK Wii will sell 7 million.

there you have it, GTA4 PS3 will be the same as MK Wii.

hm...it's hard to estimate such a thing, ps3+xbox360 users combined are more than wii, but if you consider that some people own both or that some casuals and adults will buy the game......i really can't say.....

by the way, saying that 17 million will buy GTA iv, is like saying that about 2/3 of ps3&xbox360 users will buy it, where san andreas sold 15 million with more than 140 million users for both systems combined!!

When GTAIV compined,then over MKWII

I hope Mario Kart Wii sells more than gta4.

gta4 is just for teenagers who love anarchy and want to do everything society forbids. When you think about that gta4 really sucks.

Mario Kart is just fun for everyone.

GTA4 will out sell Mario Kart Wii and any other game released this year or next year. Unless a GTA5 comes along or something (and it should), GTA4 will be the biggest selling game ever on PS3 or 360.

GTA 4 should outsell MK Wii hands down (Combined platofrms).

That would be quite an accomplishment for Nintendo if they did.

Combined yes. Alone (360) maybe, (PS3) no.

Is this actually a serious question? If you're talking about combined, no chance MK will outsell GTA.

If GTAIV is combined, then of course it will win but that is not fair. If u want to do that, then MK should be combined with something else such as MK DS

I have to go if you count GTA IV combined then it could outsell MK wii
