I feel like next year could survive without Pokemon. I think if we have at least a few heavy hitters like Smash, Animal Crossing, or Mario Maker (which all seem fairly likely imo), along with some nice supplementary titles like Kirby, Yoshi, Pikmin, and Fire Emblem, and plenty of more 3rd party support, we're good. Heck, you could even cut some of these out and I still think the Switch is fine. While most people have already played BOTW and Odyssey, I'm sure there's plenty more who haven't and those two games are so top of their class that I think they'll carry the Switch for quiet a while.
Pokken Tournament was a port as well.
