Even if there was a Pro, I don't think that you'd want to pay for it. Not if it cost any additional $$$ than a regular PS5. You start running into the same diminishing returns problems as when building a PC. They'd have to sell them for the same amount or possibly only $100 more to be worth it.
They had to cut corners on things like SSD storage just to make this one work. Xbox says they sell theirs at a $100 loss. Like always, of course.
These consoles are actually really good bang for your buck. I just wish the OS was simpler and easier to navigate. Like the PS4 and Nintendo. Not all this Snapface, connectivity, and marketing banners/notifications crap.
