We can expect any Nintendo game that already didn't realised or announced on Wii U, very hard to tell...
-Metroid
-Paper Mario
-Animal Crosing
-Luigis Mansion
-Pokemon
-Pokken
-F-Zero
-Fatal Frame V
-Pilot Wings
-Mario Sunshine HD or some other GC HD port
-New 3D Mario Game
-Pikmin 4
.....
I am pretty sure we will see at least 3 games from my list
