The evolution of the console market over time

[Pyro as Bill]

What we know is that full body motion control isn't suited to Switch Lite or the hybrid in handheld mode.

Switch hybrid sold 3m in Japan in the same timeframe that RFA sold 1.5m. Either half of those Switch hybrid sales were due to RFA or some/most of the cazulz were already there. We can also safely assume that there are cazulz that aren't interested in RFA.

RFA currently has a 16% attach ratio to the hybrid Switch in Japan despite stock issues, higher price (compared to Wii-Wii Fit) and apparent lack of console accessibility.

ARMS was above 2m and 1,2 Switch was above 3m before RFA released so Nintendo fans have probably spent as much money on 12S and ARMS as they did on Wii Play and Wii Boxing.

Ubisoft didn't bother with Just Dance 2020 on Wii-U but did make it their last game for Wii most likely because it took 10years for a system to come along that could eat into the Wii versions sales.

Switch+RFA was hitting Ebay prices not seen since Wii+Wii Fit during the pre-pandemic holidays.

Seems ludicrous to credit FIFA, Skyrim and Witcher fans when ARMS, 12S, 51CHG and RFA easily outsell them and there are still 130m DS and 75m Wii owners out there who didn't buy Brain Training or Wii Fit.

I'm not saying the uber-cazul Just Dance, Wii Fit, Mario Kart wheel users are responsible for Switch's success just that a significant portion of them are back buying their first system since Wii.
The main driver of Switch sales is the returning Nintendo casual-core/lapsed gamer crowd, some of whom were uber-cazulz during the Wii/DS days but have since crossed the bridge Nintendo built for them.
