^^^truth... they're just not released yet. Very cool "I made this - launch team edition" on the front.
There were also solid white (no black) and solid white with black zebra overlay and clear Xbox One dev kits around.
The one in the video appears to be one of the beta test units... look at the sticker placements around the console and controller. That or as mentioned... one of the internal M$ employee beta boxes for big wigs.
