If SMG2 is anything like NSMBWii, Then No contest for the others... But I think Halo Reach might sell more than both. This depends one how big Gran turismo is since GT4 is when the GT series started to decline in sales. But we will see. The user base advantage of the PS2 is what made 10 mill plus possible.

Halo Reach easily

lol silly question course its going to be gt5.

Gran turismo will sell more for sure

GT5...the box art alone is sexy enough to sell.

SMG2 >= GT5 > Reach

If SMG2 has the same run as NSMBWii it gonna be tough to beat, but since this will be the first full GT experiecne since 2005 (not including psp) and since only 1 console GT title has sold less than 10m I think it'll give SMG2 a run for it's money.

I can't imagine the hype for Reach being greater than the Hype for Halo 3 (especially since it was the first entry of the franchise on the 360). So I find it hard to believe it will top the other 2.

Reach, then GT5, then SMG2.

GT5 is a somewhat stale franchise at this point. Most people wanting that game will already have a PS3 by this point and probably will have bought GT5P.

I know it isn't smg2, it could be either halo reach or gt5, but I'll go with halo....
... but in the other side mario can give us a surprise....

All 3 have the ability to do 10 mill + but not much more than that.

So I have no idea which order they'll make it, sorry!

= Final Fantasy VII Remake confirmed?

OT: SM2 and GT5 will have massive Japan support while Reach will only have NA and Others. Racing games are also very popular in Europe, more so then America so the Ps3's lack of marketshare in NA shouldn't determine whether or not GT5's in 1st or 3rd place.

I still think Reach has a chance of being 1st as Super Mario games never sell as much as the other Mario titles but it could pull a NSMBW and dominate for weeks on end.
