I don’t understand why they would release a PS5 Pro. For the PS4 / Xbox One generation, it was somewhat justified because 4K TV became widely available and desirable shortly after the release of this generation, making the consoles almost obsolete.

This time around, I don’t see the performance of theses consoles as a big problem. Interest has declined because prices of consoles and games are high, and there are not that many exiting games to play on them.

Making a more powerful variant has some disadvantages too, making game development more complex to support all variants. Microsoft has already suffered from this strategy with the Xbox series X/S.l, e.g:with BG3 local multiplayer
