Hmm, I'm not entirely convinced that the wii wouldn't stay on top just from 3rd party games + those already announced.
Nintendogs Wii is unlikely to happen, Ninty has stated so themselves.
Wii Play sequel seems unnecessary, the first will sell long into the start of next gen
mario Zelda Pikmin kirby have all been confirmed by Nintendo :) Although Kirby is taking its sweet time
Starfox Donkey Kong F zero would all be awesome games, but Nintendo doesn't need to make them to stay on top
