Cyberpunk 2077 finally arrives in less than two weeks, although many won’t be playing the best-looking version of the game at launch. CD Projekt Red have promised full next-gen console upgrades are coming in 2021, but until then, the majority will probably be playing on PS4 or Xbox One. Thankfully, CDPR has reconfirmed that you’ll be able to start your Cyberpunk 2077 journey on current gen consoles and transfer your saves to PS5 and Xbox Series X/S whenever you happen to get one of the new machines.

Transferring your save will happen a bit differently, depending on whether you’re an Xbox or PlayStation person. For an Xbox One to Xbox Series X/S transfer, everything will be automatically handled via the cloud through Microsoft’s “Smart Delivery” program.
