Dont forget Pikmin 3, W101, Zelda WW/TP HD. :)
And Xenoblade chronicles X
Yeah, there are at least 5 strong potential Wii U ports left for Switch, so SM3DW, W101, Pikmin 3, Zelda WW/TP HD, Xenoblade Chronicles X, Tokio Mirage Sessions and Fatal Frame 5. There is also Mario Maker but I am sure we will have Mario Maker 2 on Switch.
Poor WiiU really only has Super Mario 3D World left, which I’m sure will also come to Switch at some point.
It won't, Super Mario 3D World is Wii U's 3D Mario, there is only one specific 3D Mario game for each Nintendo home console and they're never released again.
Mario 64 DS says hi, not to mention that Nintendo with Switch and 3DS is porting much more than they did before, fact that they already ported/announced 7 Wii U games in year and half, tells us how they intend to port almost every Wii U good game to Switch.
Only case that I see they will not port SM3DW to Switch is if they are working on SM3DW2, in other words, there are very good chances for SM3DW port for Switch.
