I think AC (in the first year due to the Mobile game), Pokémon, Pikmin and Fire Emblem are guaranteed to appear sometime in the Switch's life. Kirby aswell is very likely but I wish they could try to make a full fledged 3D Kirby game (Nintendo said they will be using the Zelda engine for other projects so there you go if you want to keep the costs low). Other than that we are clueless, a Splatoon sequel has to happen to consolidate the IP but Nintendo said they'll take their time so that it doesn't become as any other shooter; F-Zero and Metroid would be great but we didn't get games in those franchises for ages so it's very unlikely they will be seen (despite that I have a feeling that Next Level Games is working on Metroid Prime 4), we will be lucky if we get Mother 3 and I certainly don't expect a 4 (while I'd love to play it). Speaking of Earthbound I also have a feeling that Undertale could make it to the Switch
