Why would PS5Pro release in PS360?!?
Do you mean PS3Pro?!?
If yes then that just wasn’t possible during that gen….as proprietary hardware had a totally different architecture to PC’s back then.
There were no middleware.
Now it’s much easier to have mid gen refreshes without much of production & R&D costs.
AMD & Nvidea release a new series of GPU every 2 years.
Things are a lot different now compared to back then.
