Nintendo is in an interesting position here.
The Wii software is still selling at an impressive rate - 4 million WW and yet there are no 'new' releases.
The DS software is still selling at an impressive rate - 2.1 million WW and yet there are no 'new' releases except for Pokemon
The 3DS is now gaining rapid momentum and from here on forth, 3DS will likely dominate 2013 with the software planned (Monster Hunter 4, Fire Emblem, Animal Crossing, Luigi's Mansion, Pokemon, etc.)
The Wii U will most likely sell 3 million by year-end, however the future does not seem to bode well currently as there is hardly any software announcement for 2013. Will the Wii U Vita itself? I don't think so but there is a cloud of uncertainty that follows it for sure.
