Don't see the point yet
Maybe if you skip a generation then makes sense buy the next hardware of a console makes if this hardware is either BC or just have a tons of remasters/ports
For instance, for Nintendo gamers who never got a XBone a Series X might be a really interesting launch purchase, otherwise... yeah not really
But the main reason is pricing. Launch price in Brazil is just insanity, I'm sure I can get a PS5 in than 2 years for less than 3K, right now they are almost 5k
