Durango will also include a "high-fidelity" natural user interface (NUI) sensor. This would suggest that the console has some kind of built-in Kinect functionality, though the inclusion of a dedicated Kinect port seems to indicate that Kinect peripherals will still be available. Also of interest is the capacity for HDMI input, which Digital Foundry speculates could be used for recording or importing video from external sources like cable boxes and personal cameras.
DF offers up some more context for the leak as well, noting that there could be a significant performance gap between the new Xbox and Sony's next PlayStation, specifically with regards to its graphics processor. That's based on the blueprints and specs, mind you - we won't be convinced until we see competing real-time demos of that ballroom dancing scene from Final Fantasy VIII.
