I think Technology inside has to be put into consideration too.
By the time PS5 + XB2 launch, the Switch wont be able to play ANY of those multiplats developed for the PS5+XB2.

It belongs to the 8th gen, by the hardware & who it most likely will sell for the longest against.

No hardware isn't relevant, otherwise Handhelds wouldn't be grouped into generations with home consoles. Time is the only factor.
