Talking under the condition of anonymity, sources close to Microsoft told The Verge that the company is testing own cloud-based game streaming service.
The service is still in prototype stage and it hasn't been branded yet, but The Verge's sources have seen Halo 4 for Xbox 360 being streamed to Windows PC and Lumia 520 Windows Phone smartphone.
Sony has already publicized its plan to use Gaikai streaming service to make PlayStation 3 game available on PlayStation 4. In a recent interview, Microsoft senior director of product management and planning Albert Penello didn't rule out the possibility of an equivalent setup for Xbox One.
"There are so many things that the servers can do," he said of Microsoft's Azure cloud service. "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."
