Almost 7 years later you would think everyone who wants one, already got one.
Sales are already declining. And if Switch 2 has full backward compatibly it wouldn't at least hurt sales of games since those games will run the same but hopefully better on the new hardware.
Without backward compatibly some people might skip games in order to save it for the new hardware
Yeah my buddy just got one last month and immediately bought both Zelda games for it.
He just wanted to play them finally. If he's going to wait this long to do that he could care less about a potential new system that'll have less games.
A lot of the owners already got their system 4+ years. Likely more. People are going to look into more powerful hardware some day. Nintendo should be ahead of that and let them be the one with the more powerful hardware.
Not out-powering I know but if they have something better than now then it's easier to choose for Nintendo again instead of a Steam Deck or something similar
