The girl who spouted "skittles" every 5 seconds made me want to puke (seriously skittles!? surprised they didn't call it Boots), and the supposed "track race" in particular were pretty obviously faked.
I think the only one that might have been a true demonstration was the Wii fit knock-off.
This gives me the same feeling that the forced Microsoft store employee dance did. I'm not sure exactly what the feeling is, but hate and shame and embarrassment and disgust are all mixed in there.
Kinect is going to fail, same for move. The entire plan here seems to be: "hey, let's reproduce the wii, with games people with a wii already played 4 years ago. Let's charge a ton for all that stuff. Nothing can go wrong with THAT plan right? Drinks are on me!"
