I think the early Splatoon 3 announcement was Nintendo's way of guaranteeing everyone there would be no Switch replacement in 2022.
Hopefully that's the case, unless they want to make that one a crossgen game. (Though even then it'd surely make more sense to make it a Switch 2 exclusive)
Rumors says there will be a Switch Pro with DLSS and all new chip set coming this year. If we count that as "Switch" it could pass PS2 sales.
Why wouldn't we count a new model as Switch sales?
New 3DS counts towards 3DS sales.
DSi counts towards DS sales.
Gameboy Colour counts towards Gameboy sales.
PS4 Pro counts towards PS4 sales.
Xbox One X counts towards Xbox One sales.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
