DS - >1 Million.
3DS - 6.5 - 7.0 Million, the largest this holiday, it'll pick up a lot due to XL and Mario + last Holiday's Hit games.
Wii - 1.5 - 2.5 Million.
360 - 3.0 -3.5 Million, it'll fall by a little but get picked up some by Halo.
PS3 - 3.5 - 4.0 Million, it might become the new 360 this holiday.
PSP - 1 - 1.5 Million or less. Japan could save it.
PSV - 1.5 - 2.0 Million, it's still too expensive and there still aren't huge games for it. (I never said there weren't games for it so don't freak.)
