"Performance on last gen aside"

The way I understand all of this, Sony is pulling the game from the PS4 store but promoting that it's available on PS5 with additional patches.

CD Projekt Red also already said that getting the PS5 port ready for launch will take all of their capabilities. So it might be a deliberate move to sacrifice the PS4 version in order to improve the PS5 one.

I mean Sony clearly has a financial incentive to push the PS5 onto the market and to make players abandon the PS4.
