This is it: The Oculus Rift specs are finalized, and we go hands-on with the engineering sample of the consumer virtual reality headset at this year's E3. We also demo the new Half Moon prototypes of the Oculus Touch controller in an amazing multi-player VR demo. Oculus' Nate Mitchell and Palmer Luckey answer our questions about the headset and controllers, and we share our impressions of the hardware and game demos. It's happening!
