There is one more thing: they faked voice recognition:)
Why this Yusuf guy is always getting his hand to his pocket, when he is saying something to Xbox One? Is he switching slides? Maybe he is activating voice recognition by remote hidden in his pocket? See for yourself and tell me what you think.

It starts from around 9:35

Why put something in your pocket when it could be done off stage and no one could tell, he says what he wants the Xbox to do before it does it, I could press a button from my PC while watching the stream to coincide with what he says to give the impression of voice recognition, lag might be an issue though!
