I say that all this OS RAM talk is legit but I also think that MS has a strategy lying beneath: The app-concept. I don't think that MS will reserve 3 GB RAM for OS-purposes but I think it will open the XBOX Os somehow to their windows store where users can download apps as they like.
You can already download apps on the 360, but I don't see Durango having full access to the Windows Store unless it ships with a touch panel or a mouse (which I don't think it will). Emulating those input devices with a controller or Kinect would be cumbersome, which would defeat the whole purpose, and native support for controllers and Kinect is not something that's required from already existing apps.
