The Day One Edition includes a commemorative controller, with appropriate inscription smack dab in the middle: "Day One 2013."

The design of the Xbox One controller builds on that of the Xbox 360 controller, with a few updates.

The development cost for the Xbox One controller exceeded $100 million, according to a Microsoft representative. Some of the prototypes featured built-in displays and cameras, a cartridge for emitting smells, and even a built-in projector.

Also tumbling out of the, er, box: the Kinect 2.0 unit and a miniature Xbox One enormous power brick.
