Imagine the Series S was Nintendo's next console. For $299. We'd all be happy. If Wii U games had been ported to be 4k/60hz on Nintendo's Series S, I'd have been happy, instead of just Wii U to Switch games barely improved, I would have been excited. Hopefully Nintendo still has a future product for me. Someone that has been waiting since the Wii U died to get excited again.
While I can definitely understand the appeal that a dedicated Nintendo console on par with Xbox/PS has for a lot of us, I don't think it would make much sense for Nintendo; the whole point of the Switch has to unify their production pipeline and console/handheld divisions into a singular piece of hardware. To now make a separate console on par with Series S would require a ton of R&D, and undo that unification, meaning less games and the same droughts that crippled Wii U.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
