The news came from the Cyberpunk 2077 Twitter account, in response to Xbox posting about the Xbox Series X's backward compatibility.
"Gamers should never be forced to purchase the same game twice or pay for upgrades. Owners of #Cyberpunk2077 for Xbox One will receive the Xbox Series X upgrade for free when available."
Details as to how this promotion will work have not been released. It's possible that anyone that connects the game to their Xbox Live account will be credited for a digital copy on the Series X. We assume that additional information will be revealed over time.
This is a surprisingly kind-hearted decision to make. There have been countless folks who have mused for this exact idea, firmly believing that a company would never do such a thing.
This news also soothes the wounds of Cyberpunk 2077's recent delay. Originally set to release March of next year, the highly anticipated Sci-fi RPG was delayed until later this year.
