Xbox One could - in the future - offer backwards compatibility via the cloud, much like PS4 service Gaikai, Xbox's senior director of product planning and management Albert Penello has told GameSpot.
Asked whether the cloud could be used to offer backwards compatibility, Penello responded: "Yeah, absolutely. That's one of the things that makes [the cloud] at the same time both totally interesting and hard to describe to people."
He added: "There are so many things that the servers can do. Using our Azure cloud servers, sometimes it's things like voice processing. It could be more complicated things like rendering full games like a Gaikai and delivering it to the box. We just have to figure out how, over time, how much does that cost to deliver, how good is the experience."
Xbox One will launch November 22 priced £429, but act fast if you want a unit for day one.
It's pretty clear Penello isn't saying backwards compatibility is confirmed to be coming in the future, instead stating that the cloud is so versatile that such a service is possible to implement.
