Microsoft has announced a pretty cool feature for the upcoming Xbox Series X called Smart Delivery.
What this feature does is take your game from the Xbox One, and upgrades it for the Series X system. This means your older game looks and runs better and the new console, plus you get to keep your save data.
This is especially useful for games coming out just before the Series X launches. If you buy Cyberpunk 2099 for the Xbox One, you can transfer everything to the newer, more powerful system.
The only disappointing side to this story is that Smart Delivery only works on certain games.
