This is mainly just looking at it being different consoles in the space. The Switch 2/PS handheld/Xbox handheld won’t have to compete on who has the best hardware, for Nintendo games you get the switch, PS games the PSP, and game pass you get the Xbox.
As for future PC handhelds, there will be linear improvements (better performance, better battery life, etc), different UI options (SteamOS versus windows with some program slapped on top), and different use cases (smaller more portable devices, etc).
