Wii/DS each had ten 10-million-plus sellers. Switch has five and it's not even 2 years old

I'd have to say yes, at this point. Given how strongly key Nintendo franchises are performing, it's a good bet.

Already over 10m:
Mario Kart 8 DX, Super Mario Odyssey, Smash Ultimate, Zelda, Pokemon Let's Go

Should hit 10m, probably in 2019:
Splatoon 2, Animal Crossing, Pokemon Generation 8

Could hit 10m:
Super Mario Party

We're up to 8 practically guaranteed 10 million sellers and a possible ninth in the shape of Super Mario Party just by counting games already on the market or already confirmed. I'd expect Super Mario Maker for Switch to have a good shot at 10 million too, plus a Let's Go Johto version in 2021 to take it to 11. It's difficult to know beyond that - but sequels to things like Odyssey (or simply a new 3D Mario) and another version of Mario Kart might do the trick, depending on how long Nintendo keep Switch going.
