Wow, I completely forgot about Metroid Prime 4 already, I guess that's because they basically didn't show anything but a title screen yet :/
Anyway..
Metroid Prime 4
Yoshi
Kirby (reviewing for the site!)
Octopath
Mario Tennis
DK: Tropical Freeze (Portable + Funky Kong mode!)
and most definitly all 3 of those maybes if they happen (which I'm sure they will at some point):
Smash
Pokemon
Mario Kart 9
