Hardware
Wii 7 million(Going by how fast it dropped this year and DS this year)
DS 5 million(Nintendo know how to kill hardware)
3DS 17 million (I'm going to assume their will be a redesign and a 2D mario released in the holiday)
PS3 13 million(I'm guessing it will start going down because it won't have a another price cut)
360 13 million (Guessing their will be a price cut since its last one was 08 also America will be up yoy)
Vita 9 million (Typical PSP numbers)
PSP 5 million (The decline continues!)
Ah wii U
Wii U 1.5 million(No way Nintendo will not release it in the Holiday season.)
