Amiibo Universe for Wii U + 3DS (coming October 2015)
Metroid U
Diddy Kong Racing U
Hyrule Warriors 2 (will also be on next-gen Nintendo portable)
Pokken Fighters (not officially announced yet right?)
Generic Mario Sports Game
Paper Mario U
Splatoon DLC Expansion

Are my guesses, that will pad out Nintendo's 2016 lineup for Wii U.

Animal Crossing and Mario Galaxy 3 (or whatever the next 3D Mario) are for the next-gen Nintendo portable launch window IMO (sorry Wii U).

I will also guess Punch-Out! 3D for the 3DS this fall from Next Level Games. That will help fill out the 3DS lineup. Makes a lot of sense for the 3DS too, Punch-Out is a series that is tailor made for a 3D screen. 

I agree with you on 3D Mario, but I can't see Animal Crossing skipping a system.  As for Pokken, yes, we have not yet heard it be officially announced for Wii U, only arcades.
