More alleged leaks are pointing to the console having an always-connected format with games to be installed directly to a hard drive



From Techradar:
A supposedly leaked document from the Durango XDK dev kit outlines that the console will also have a Blu-ray player and a high-fidelity Kinect Sensor that will be needed to operate the console. However, once games are installed there will be no more need for a disk, with all gameplay happening via live internet connection.
