Nintendo seems to release roughly one of these experimental type games per year; last year it was Mario Kart Live, in 2019 it was Ring Fit, in 2018 LABO.
They're fairly low risk as they don't have the budget of a BOTW, Mario Odyssey, or Xenoblade, so it's not a huge loss if they don't take off, but if they do (see Ring Fit) they're a big win.
