Just weird.
Speculation:
1) when drivers open you hear a sound that looks like a dvd driver being closed...
2) when driver closes theres a weird sound....
3) theres a small device that turns on a red led (is it the power 'brick' thing?)
*edit*4) Also when he turns xbox on theres a sound that looks like a dvd drive opening.. i dont know how xbox 360 sounds like but that makes sense if they used 2 xbox (power both xbox visible using power buttom, the hidden one using open button)
5) theres a 'thick' sound just after the "other" xbox opens that could be the other guy placing the disk on tray
After two failed attemps they had to show something more interesting than this.. and its so simple to prove, just put a wired crontroller, show all the wire and move a lot in game showing both tv and controller at same time...
Well... it could be a second xbox or just a white painted original disk....
Ya when he hits the power button it makes a funny noise and when they close it, it sounds like there is another drive closing in the background.
