MewTwo
Freeing Pokemon From Their Masters Since 1996
3D Mario and Spla2oon are a given.
3 and a half games have been confirmed for the NX so far:
Breath of the Wild
Just Dance
Sonic Generations 2
*Dragon Quest XI* (Square Enix let it slip during the reveal livestream, afterwards they've said it's being "considered" and haven't talked about the game since.)
People thought '3d mario is a given' when it came to the Wii U and all we got was Mario World 3D. (good but not as good as Mario Galaxy)
Breathe of the Wild needs to be exclusive to the NX to get people to buy the new hardware. Unfortunately it's also coming out on the Wii U.
No one cares about the other 3 games you listed. lol @ Just Dance. Come on man.
