The moment I saw 1-2 Switch I thought to myself "Why the hell didn't they just make a Wario game?" lol
Seriously, they seemed to be trying to capture a sort of manic, fun, party atmosphere with the 1-2 Switch (definitely fell short), and what series is more perfect for that and for motion controls than Warioware? It's so obvious that it actually irritates me that Nintendo didn't see it.
Otherwise, until they actually make an F Zero I'd recommend just playing Fast RMX muted while playing F Zero music in the background.
*Edit* This one really should have come out on the Wii U (the only game I thought was perfect for it), but I think another Pokemon Snap would be neat, as if it's still essentially a rail-shooter with puzzles (akin to the minecart portions of Captain Toad) the gyro controls in handheld mode would be perfect for it. Heck, with the improved technology they might actually just be able to make a few large, three dimensional environments you can walk around in looking for the best pictures. Of course, they could also maybe just include this feature in their upcoming Pokemon game lol
Otherwise... the Switch desperately needs a Mario Maker game, perhaps with a packed-in Stylus to make level design on the touchscreen easier. I've no doubt that another Smash (improved port or sequel, the former being more likely) is coming...
Really, if theirs one "out of left field" game I'd love to see, it would be another Nintendo-SquareEnix collab for a proper Super mario RPG sequel. Kingdom Hearts (though I don't care for that franchise) has showed how well collabs and crossovers can work, and everyone who has played Super Mario RPG has loved it; that's one type of game we really don't get from Nintendo, and with how drastic and successful a departure from the norm Mario + Rabbids is, I hope that motivates them to do more such projects.
As for third party... They should throw whatever money they have to at Blizzard to get Overwatch ported over to the Switch. Unlike many of the top competitive games, Overwatch sports Blizzard's typical, masterful optimization to allow lower specs to run it, and a port is definitely feasible. I'm only a moderate fan of the series, but it would be a big boost for the system, especially if they allow for cross-console play (which seems likely).
