Welcome to the Game Universe. My name is Joshua Ewell and I am the Solo Indy Developer for the games produced here. I build video games using Unreal Engine 4.
Although Cyberpunk 2077 will be published in future independently on the Xbox X and PS5 games, the developer CD Projekt Red has stated that fans would not support it for the current device. Instead, once the consoles are in service and when Xbox One, PS4, Mac, and Stadia models are announced they can move farther into the list.
Nowakowski clarified as well that Playstation did not state whether PS5 accepts improved PS4 games (similar to Microsoft's Xbox Series and Xbox One), and it will not have a clear identity as to how PS5 will play Cyberpunk 2077 in an improved PS4 update. CD Projekt Red has already announced that an update to Cyberpunk 2077 would allow Xbox One users to upgrade to an upgraded version of Xbox Series X for free, but the same can not be said (for now) for PS4 and PS5.
Nowakowski has stated that Cyberpunk 2077 is still on schedule for release on Xbox One, PS4, and PC in September. No proposals to postpone the production of the game are currently in place.
