Theyd be foolish if it was a big jump in power, they make money through software and not hardware.
Seeing as people gladly paid more than this to scalpers, id say they will definitely try.
I expect it, but i also dont expect it to fully replace or be as succesful the normal 500-550€ ones and just be an extra offering. If it happens itll likely be a small and very cheap jump in specs.
They will likely end up being nearly identical (ram,cpu) and just have a better gpu, psu and more storage since those are the areas where the current consoles are struggling. Well those and the cpu performance, possibly because all the power goes to the gpu and zen2 single thread performance is pretty weak, but that should be solved on the software side (they target low framerates anyway, ryzen 2600x tier performance should be enough if its fully utilized)
Wouldnt they be dumb and make things more complicated if they improved the ram and cpu? Having diffrent gpus shouldnt make things any more difficult unlike Series S and X having different amount of ram, it has to be pretty bad to work on those.
