No no no no no no no no and no. PS2 numbers over 100 milion units so less than 10% attach rate for GT4 bit higher for GT3 but when GT3 came it had no racing game that could be compared to it. Halo 3 had over 50% attach rate when it came (and still around 25%). And Cod MW2 has sold faster than Halo 3 (on 360 alone) and yes Halo Reach will sell more for 360 than MW2. So this is about as likely as PSP-Go outselling the 3DS.
Edit. Also like to add that Halo: Reach is gonna sell more in the first week, than KZ3 will do lifetime sales.
