Colour us shocked. Joystiq's reporting that the Boom Blox head-tracking feature - that was supposedly going to allow players to move the game's camera with head movements - has been pulled. From the site:
At the Nintendo Media Summit, Boom Blox senior producer Amir Rahimi confirmed that the final version of the game will lack the head-tracking mode. We understand that it was always an Easter egg, requiring gamers to set up Wii Remotes as cameras, and hacking together their own IR LED glasses. But you didn't have to go to TED to see the promise, and we're disappointed to see it removed.
