Sony's upcoming next-gen console PlayStation 5 won't have a feature similar to Xbox Smart Delivery according to latest reports. Sony will leave to publishers to decide whether they want to support the "free upgrade" program, though.
According to Sony Interactive Entertainment (SIE) spokesperson, who talked to Japanese website GameSpark , Sony will not have a program similar to Xbox's Smart Delivery, which would allow players to upgrade to the best version of the game if they previously purchased a product on the last-gen console.
Sony spokesperson said (roughly translated by Google) that the company plans to "flexibly support the upgrade plans (of publishers) provided by each title", but there is no "uniform standard such as the Smart Delivery adopted by Xbox Series X and it is up to the publisher to decide whether it is supported, how it works, and any additional costs."
This basically means that Sony will not stand in a way if a publisher wants to offer their game for free on PlayStation 5 if players already own the PlayStation 4 version of the game. However, they also won't push for such a program with their own Smart Delivery alternative, which is something that some players could find disappointing.
As you may know, Xbox's Smart Delivery will support all Xbox first-party studios along with some third-party games such as Cyberpunk 2077 and Assassin's Creed: Valhalla. The full list of supported games, that will be expanded with new titles can be found here.
