Hot take: this will fail. Just like HD Rumble, 1-2-3 Switch and Labo and any other attempt Nintendo does to try to recreate the Wii. The Switch is a huge success because it offers great games that can be played on a console or a handheld with one purchase. But I assume there is one stubborn Nintendo exec who keeps pouting and insisting on pushing this crap despite the fact that this was all a fad that died out nine years ago.
The Switch is a hit. All Nintendo has to do is continue to make great games, which they're better at than anyone, and the money will roll in for the next few years. No need to get cute with dumb gimmicks.
