The developer further clarified that this would not be the final update to buff the next-gen version of Cyberpunk 2077. A beefier version of the game optimised for Microsoft and Sony’s new machines will follow down the line - perhaps some time down the line - but again be available to PS4 and Xbox One owners free of charge.
“I can confirm this is not the final update,” CD Projekt exec Michał Nowakowski said. "At some point we will have a more robust update for next-gen which we plan to give free of charge to anyone who purchases the PS4 or Xbox One version.
“But in any case you will be able to play the game on next-gen from 19th November when the game releases and it will look better than on current-gen from that moment as well.”
So that actually suggests you will get the PS5/XBX version if you have the PS4/XBO version, at some point, so maybe not at launch…
