The future of the Xbox brand is "cloud centric" rather than "device centric", according to Phil Harrison, corporate vice president of Microsoft's Interactive Entertainment Business.
Speaking today in London, the exec said that the future of Xbox will be games that are accessible on multiple devices.
Harrison said that Windows 8 has extended the Xbox experience out of the living room, with an increase in the use of Xbox as a brand on supported platforms including PCs, laptops, tablets and mobiles.
"Increasingly, the games are going to sit on the cloud," Harrison said. "Instead of being device centric, they will be cloud centric.
"This vision is what influenced me to join Microsoft in the first place," he added.
