What the Next Box should have?
It should have the NT kernel. Bringing all Microsoft products on the same page.
Backwards compatibility, be able to play old games on it. But new games should not be able to play on the old Xbox.
It should be able to use WiFi/Bluetooth to send the footage of the game running on the Xbox to a windows 8 device. Kind of like the Wii U. So you could play Xbox anywhere in the house.
Skydrive and Skype built in.
Illumiroom included plus next gen Kinect with its own processor
Bluray for the bluray niche group.
