I think Consoles are going the way of PCs and mobile devices; Regular (maybe even yearly) updates that increase power but don't break compatibility; and are "forward compatible" for at least 5 or 6 years.
The Xbox Series X announcement kinda cemented that for me. They hinted it's just one of many models of Xbox they might release / announce.
For Nintendo, I wouldn't want them to release a Switch 2 necessarily, but they could do what Apple does and have a Switch pro that a few years down the line becomes the regular Switch, with a new pro device taking the top end of their capability
