Looks like it's going to be the largest drop in video game history. Well between that and the 3DS.
Wii: 100 million
Wii U: 17-18 million (estimated finish)
PSP: 80 million
Vita: 17-18 million (estimated finish)
DS: 150 million
3DS: 68-74 million (estimated finish)
Sega Genesis: 40 million
Sega Saturn: 10 million
Smartphones/tablets have decimated the Wii U, Vita, and 3DS IMO.
