"We see on other platforms, whether it be mobile or PC, that you get a continuous innovation that you rarely see on console. Consoles lock the hardware and the software platforms together at the beginning of the generation. Then you ride the generation out for seven or so years, while other ecosystems are getting better, faster, stronger. And then you wait for the next big step function.
"When you look at the console space, I believe we will see more hardware innovation in the console space than we’ve ever seen. You’ll actually see us come out with new hardware capability during a generation allowing the same games to run backward and forward compatible because we have a Universal Windows Application running on top of the Universal Windows Platform that allows us to focus more and more on hardware innovation without invalidating the games that run on that platform."
"We can effectively feel a little bit more like we see on PC, where I can still go back and run my old Doom and Quake games that I used to play years ago but I can still see the best 4K games come out and my library is always with me. Hardware innovation continues while the software innovation is able to take advantage and I don’t have to jump a generation and lose everything that I played on before."
Spencer essentially says that we should not expect the release of an "Xbox Two," since the Xbox One will be upgraded over time like a PC, but with games developed on the Universal Windows Platform system, which would stay backward compatible despite new hardware.
Spencer added that the Universal Windows Platform, a common development platform that allows apps to run across PC, Xbox, tablets and smartphones, would be central to the company’s gaming strategy. "That is our focus going forward," he told reporters. "Building out a complete gaming ecosystem for Universal Windows Applications."
The Xbox chief also promised that UWAs will support multiple different graphics processors and that issues with V-Sync would be resolved.
