Weird take because of how much they have experimented with entire consoles in the past. I don't know how the Wii could be called betting on withered technologies.
I for one like every genre but I find it unfortunate nintendo has a wierd focus on casual age friendly games.
Almost any gamer who has played a fallout, diablo, mass effect or RD game also owned a wii.
One of the issues with the Wii was that the controller tech was too immature, hence the later addition of the MotionPlus stuff, and how the Switch versions of "use it like a pointer" games are so much more robust.
... but as peer threads have noted, this is a relatively new vector for them in terms of value brought to the marketplace. They were competing on grade-A computing and graphics tech in the console space, but did the math and (IMHO wisely) concluded they weren't going to win that fight against Microsoft and Sony (and the manufacturing deals MS and Sony could cut and the manufacturing they could do in-house). So they instead noted those two firms were competing on making the same kind of game and pivoted to providing a platform to make the kinds of games they couldn't put on those consoles (but were starting to show up in arcades, where the inability to compete with the home console market had led to the need to incorporate more interface gimmicks).
