Well, first of all I hate the term "non-gamers". They play games, so they are gamers. Whatever the self-declared super duper elite hardest of the hardcore think and say.
Secondly I don't see it. Catching the Wii-folk could be easy. A new Wii-sports like game, they already do have the Wiimotes build in as Joycons. There are 100 million people that followed that path. Even if they bring in only a fourth it is great, because these 25 million could combine with other players, as Switch support also different playstiles. But no, I can't see them doing it. Whatever people say, Labo is great and all, but it is no Wii-sports. And so far I see no sign from Nintendo they are doing that.
