You keep dismissing the Switch 2 like it's a known quantity. But even if we assume it's "only" as powerful as a PS4, how could anyone argue that a bog standard JRPG that often looks no different than FF15 couldn't be ported to such hardware? PS4-games could be ported to Switch 1, it's reasonable to assume that PS5-games can be ported to Switch 2. More easily, probably, thanks to DLSS and generally more streamlined technological progress. "Dumpster fire" is such a crass word of choice for what should be a perfectly fine port. Why even say "Switch 2 will be VERY limited in power compared to current gen consoles", when the gap between Switch 2 and PS5 will by all rumors and leaks be less than the gap between Switch 1 and PS4?
Really weird claims.
I don't know if that's hyperbole or just an uninformed take... But XV had an almost flat open world with VERY limited geometry. Any person with two working eyes can see how much more demanding Rebirth's areas are, due to the more complex geometry, texture/materials variety, faster action taking place, etc.
And I'm not even saying a Switch 2 port would be impossible, as graphics are the most feasible aspect of a game to scale. But if it's close in power to a PS4 it would not be a simple port, especially if it uses flash memory of a similar speed to the OG Switch's.
