Halo: Reach to be biggest game of 2010 “across all platforms"

[Cheat1011]

I'm pretty sure MW2 is going fuck Halo 3's sales in the ass, but I see Reach outselling the 360 version of MW2's first week, perhaps 5.30 million. The only thing I see giving Halo trouble is CoD, I'm 100% positive GT5 will not reach the other games' amount of sales.
