Zelda, Xenoblade, Starfox, Fire Emblem, and 1 or 2 unannounced games.

Wii U

Zelda
Star Fox
Xenoblade
Splatoon DLC
Mario Maker
SMT x FE
New title
Remake (possibly Super Mario Sunshine)
Several indies and smaller digital titles like Dr. Luigi.

3DS

Pokémon Z
Fire Emblem
Metroid
New title
New 3DS exclusive (far from being as big as Xenoblade)
Several indies

They'll also focus on the smartphone games they're planning on developing.

This year there wont be a Pokemon game on the 3ds.

Zelda Wii U
StarFox Wii U
Xenoblade Chronicles X Wii U
Devil's third Wii U

Metroid 3DS
F-Zero 3DS
Earthbound 3DS
Ice Climber 3DS

i can see a metroid remake on the 3ds

I would add to Wii U: Devil's Third, Project Treasure and Mario Sunshine remake or something Mario related, but not a new Mario. Also, some other remake and a racing game.
I would take out SMG 3. Don't really see Nintendo making a third game. At least not in this gen.

I dont think animal crossing for Wii U or metroid for 3DS, but i think metroid for Wii U, and the rest is preatty much accurate, maybe not Super mario galaxy 3

For Wii U, I expect we will get trailers to hype up the coming exclusives as well as gameplay streams. Specifically:

Xenoblade Chronicles X
Zelda
Star Fox
Devil's Third
Mario Maker if it isn't already out
Yoshi's Wooly World
Potentially one other game not announced yet.

There will probably be a number of things announced or elaborated on. Specifically:

Rodea the Sky Soldier
Project Treasure
A Prime style Metroid
Animal Crossing
A new 2015 game, probably smaller
Wild card: 3D Mario, F-Zero, something like that.

We'll also probably see indies get talked up a bit. Fast Racing Neo hopefully, Freedom Planet, and a few other highlights.

I also wouldn't be surprised if there was a Splatoon tournament for hype reasons since it will be recently released.

SMT x FE is another possibility

Diddy Kong Racing 2

Wii U possibilities -

Metroid U, maybe Luigi's Mansion 3, Mario Tennis U, Pokken Fighters for 2016. SMT x Fire Emblem will be absent (moved to NX).

3DS possibilities -

Punch-Out! 3D, Diddy Kong Racing 3D, Pokemon Z debut.

Amiibo Universe game for both Wii U, 3DS, and coming to NX in the future. Will also have a smartphone-ized version on iOS/Android as well.

Mario Maker will be on both Wii U and New 3DS. 

Nintendogs, Brain Training, Mario coming to iOS/Android, Zelda and other IP later.
