I'm still on the fence (yes, I'm aware it's coming out in 4 days) but so far what I'm seeing is:
-Fast RMX (because that's pretty much F-Zero, and F-Zero is good)
-Zelda: Breath of the Wild
-Super Mario Odyssey
-Mariokart 8 Deluxe
-Super Bomberman R
That's it for exclusives, at least. If I do pick one up, I'll probably end getting the Switch versions of Rayman, Yooka-Laylee, Sonic Mania, Steep, blah blah blah. My biggest concern at this point is "yeah, what else?" A new 2D Metroid? A new Donkey Kong Country? We aren't demanding them at launch but at least give us some idea of what you're cooking up.
