You are aware that old consoles still play games, right? My PS4 still plays all my PS4 games and lets me stream PS5 games to from my living room to my bedroom. My Xbox 360 still plays games just fine last time I checked (last June or so). Getting rid of old consoles doesn’t make sense unless you absolutely have to have the latest tech and also don’t have much storage space.
Nintendos had 3 generations in that time and Xbox has had countless churn in its hardware.
