Honestly Nintendo should've just released "Wii 2" in fall of 2011.
- Wiimotion Plus in every box
- 2x-3x the raw graphics capability of a PS3/360 w/2GB RAM
- Zelda: Skyward Sword and The Last Story as a launch titles (1080p resolution).
And then rolled out Nintendo Land + Wii Tablet Pad in 2012 for $99.99 (ala Wii Fit) as an accessorie and maybe made an optional Nintendo Land/Tablet Pad bundle for 2012.
It may not have been the most inspired route to take, but they'd probably be sitting pretty with a 12-15 million userbase right now even if the system had some sluggish sales periods.
Looking at the Wii sales, Christmas 2010 seemed to be the last big holiday for the Wii. They simply waited too long. The 3DS having so many problems out of the gate really set them back too, I think they became entirely fixated on that problem.
