All the games in that trailer will be on Switch IMO. Nintendo is too damn cheap to make "mock up" fake games for a commercial video. The only time they really ever do that is the usual "Zelda tech demo" they did for the N64, which then kinda became tradition for the GCN and Wii U.
I remember when they first showed the Wii U and people thought the NSMB game and all the little Metroid mini-game thing and the Wii Sports stuff were just demos, not real games ... but basically all those did get released ... NSMBU, Nintendo Land, and even Wii Sports Club.
