Switch is definitely entering the retirement age phase of its life cycle, 75k is way down, next year would be ugly but they're going to probably have Switch 2. Not bad for a system this old, but Nintendo can't go long with a system in decline when they only have one hardware line.
Mario Wonder not boosting the Switch that much, I think the audience of people that were sitting around and not buying a Switch for all the other Mario games was overstated. It's not the Wii era anyone, the "oh noez, I can't play 3D Mario" crowd is not that large anymore, most Switch owners grew up with a N64/PS1 or PS2/GCN. As such you can see 3D Mario has closed the gap to the 2D Mario games by a lot if not entirely.
