I think it's difficult to know where we really are in the release cycle for this console, as it's been disrupted so much by initial unavailability and COVID. Normally, we'd be due a Pro version this year, but it could be this year, it could be next year, it could be never.

Last generation I was happy with a standard PS4 until I played Control, and could see that it was struggling. I'm not sure there's any PS5 games that are known to stress the hardware, and would do anything with the extra resources.

I'd buy one now if I were you. Worse case scenario: you'll want to trade it in for an upgrade in a year or two.
