I don't even think it is a matter of no PC.
Look at the Steam hardware results. If you get Series X games on your PC 9 times out of 10 most of them are going to be playing at inferior settings.
I think that is what people need to understand. Not everyone has a gaming PC, and even LESS have a gaming PC that pushes better visuals then the XSX will push.
Everyone acts like the PC is a completely issue free alternative to the Xbox. I'm a PC gamer and I can tell you it isn't clean cut. Driver updates, Windows potentially destroying your SSD, hardware incompatibilities, etc.
It is NOT everyone's cup of tea and I honestly believe most people who say 'PS5/PC' have potato PCs. Hell the Steam hardware stats pretty much prove this.
