Following this, if Sony cannot figure out a way to get away from 18 and 36 CU, their next device would need to be 72 CU and have everything else beefed up t support it. 54CU should have been the number maybe, but now that they are releasing PS5 at 36 their path may be locked now to multiples of 36. It's unlikely we'll see pro editions this year unless 1000GB/s bandwidth comes down dramatically in price in 2-3 years, not to mention you're going to have to maintain that clock rate of 2230Mhz... that is based on the activity load and not thermals. They are pretty much bound now.You'd be daft to go narrow and clocked high if you didn't have to.
I do feel for the Sony fans who don't care for BC, they are right that BC held them from seeing a higher potential PS5. I have no idea what the future will hold for the next PS device. This problem needs to be resolved.
