With the PC ports is a matter of "what are they losing by doing it?". Clearly the PS5 keeps selling out and they also had the Xbox as a reference that people don't stop buying the console just because those games are also available on PC. It seem like the public that plays on PC but buy PS5 just for exclusive just isn't that significant compared to the public that have a PC, won't consider buying a console but is willing to play those games on PC. Sony never made any public commitment to it, they tested the waters and so far it seems to have worked out well for them.
For me.... it's an incremental thing.
Each game is a reason to buy a PS5 and they are giving them away one by one..... instead of adding to them....
They should be adding reasons to buy rather than eroding.
Add From Soft, add Square.... add Arc System etc etc.
As I said I have no issue with GAAS going to PC or even Xbox sometimes.
