huh so kinect anticipates the future xD

Wow how could anyone spin that.

Also when nintendo staged wii sports a member of the audience played it with Miyamoto and company. 

BOOOOOOO  it was fake ,  lool 

That is quite clear then....

My main concern was the Ubisoft fitness thing. They seemed to be moving in opposite directions, any explanations of that?

What is the point in this thread really. If you don't like what this peripheral brings to the then don't buy it and stop reading into it so much because all your doing is proving is that you do in fact give a flying fuck about it.

The image is mirrored.  It is because you are looking at a screen that is behind the person playing.  What she is looking at makes sense.

But her right hand is moving, and her avatar's left hand is moving

You have to image controlling it yourself.  When you are standing in front of that image and the menu item is to the right of your body, you will move your right hand to activate it.  The avatar on screen will be moving the left hand.  Just like looking at a mirror.

I thought it might be something like that, but that is also slightly confusing in some ways, but that is certainly a valid explanation, and actually works much better than if it was direct

That's it man.  Thanks!  I put this in my OP if that's alright.  If not, let me know and I'll take it down.
