Ok, guys, we have to get past this notion that there is some kind of "learning curve" to develop for the PS5. It's the same architecture as the PS4. X86 plus the same graphical API, only bigger, faster, stronger. It;d not like learning the ins and outs of the PS3 when coming from PS2 development. It's the same. Just add more polygons and textures. There are no secrets. Demon's Souls looks and plays amazing because they had experienced developers working to make the game as great as it could be with all the necessary knowledge.
The best mid-gen change they could make would be discontinuing the Series S. That thing is like a cinder block tied to each ankle of the Series X as it races against the PS5.
