Microsoft's Xbox One is promising even more second-screen support than we saw on the Xbox 360. An improvement of the SmartGlass integration we've seen pop up on the Xbox 360, Microsoft says it can make your mobile device feel like it was "built" to work with your console. The current SmartGlass app has seen over 10 million downloads, and it looks like Microsoft is aiming for more this time around. It will also be able to screen scrape video, encode it to h.264 and send it over to your second screen, although what will work on which devices is still unknown. What is mentioned in the press release is that it will support multiple devices at once, for multiplayer and shared entertainment. It's also promising exclusive experiences with its NFL partnership that attach to SmartGlass and Skype integration, so we'll expect to see more about that in the future.
