DS and Wii domination really only depends on the sales of PSP, PS3 and the 360, they need to decline as they just cant make thoses Wii's. althought I expect production is up but being help back for Christmas. I think the PSP, PS3 and the 360 sales will all now decline as no Halo, price cuts done for PS3 and PSP nlite sales boast is coming to an end.
