Wii U is a great console that people aren't given a proper chance to. That isn't gonna change easily. That's why if Nintendo wants to make Wii U a success, they need to encourage out of the box thinking everywhere they can put it. No safe choices at all.
I would start with a Zelda MMO
Next I would release the most popular of the core franchises, Mario Kart, Smash Bros and a few casual bombshells like Wii Fit U.
Then I would have the mario and Retro teams make new franchises and the only instruction I would give to them is "do something crazy", and "no safe choices".
I would try reaching out to microsoft and sony as well. Tell them I wanna make a Nintendo vs Microsoft vs Sony MMO game or something similar.
If they want to make Wii U a winner they have to go far out of the box. I think Nintendo agrees with me, but it's too big of a risk for them, so they are cutting their losses this gen and just doing the bare minimum.
