Where the hell was I when Uncharted 2 sold over 4 million in its first week?!? 
Anyways seeing as Halo Reach is already at 6.45 million I think it will get to 8 million by the end of February 2011 And by the end of next year it should be around 10 million.
It may not be as big as GTA, Pokemon or COD but I do think its a bigger game (in term of sales) then Gran Turismo.
