What is the Future of the Switch?

With last week's announcement of Super Smash Bros. for the Switch, it got me thinking about what kind of system seller titles Nintendo still has in the wings. The already announced Pokemon and Smash are probably the two largest options. Animal Crossing will likely eventually move some units. But other than that, I imagine they might have to rely on a new Mario Kart, Mario (Super Mario Odyssey 2, perhaps, going the route of Galaxy), and Zelda (a Majora's Mask to Breath of the Wild's Ocarina of Time) before the generation is done.
