I will state this is a stretch but interesting things might be available to the Xbox one. Today MS released information about Windows 8.1 blue will have native Miracast (basically Airplay). Miracast uses Wi-Fi Direct which the Xbox one has included. Now that Windows 8.1 will also have native Miracast, its very possible for MS to stream games from your PC to the X1 like Nvidia's Shield.
If anything, MS will be able to stream games from the Xbox one using probably xbox glass to supporting devices that have WiFi Direct. So with MS TV functionality and Snap feature, you wife can be watching her favorite TV or movie while you on your Tablet/Smartphone could be playing your Xbox one game. Potentially you probably could also have the Xbox one send its game to your PC screen if you prefer your Dual screen monitors.
