Those sounds nice, but I think we can expect those:
-More info about Xenoblade Chronicles (N3DS) and Xenoblade X (Wii U)'s release, maybe they'll also add some freebies like they did with Xenoblade Chronicles back in the Wii era
-More info on that StarFox game
-Some N3DS exclusives just to make original 3DS owners mad
-More Wii ports (That'd be a great idea to port OpRainfall's games to the Wii VC. Especially given how much they cost now
)
-More info on Zelda U
-More amiibos (I feel like they'll do it) ?
Possibilities:
-A new Metroid game (as you said, that'd be great, especially since how good Prime Trilogy is)
-Amiibo Adapters for Regular 3DS
Unlikely/Impossible:
-Pokémon Spin-off/Main Game (Because of Shuffle...
)
-SNES VC for 3DS (In theory, the 3DS could emulate the SNES without any problem, but the problem is Nintendo. And by 3DS, I meant original 3DS too (I guess I don't need to explain why))
-F-Zero Game
-GameCube VC (I know they won't do it anytime soon)
-Region-Unlock (for both the Wii U and the 3DS, yes, I can dream...)
Honestly, that's my predictions. Some of the ones you posted might happen, but I feel like some of them just won't happen.
