ok everyone say it with me now.
All 3 systems are capable of 1:1 in the hardware. The fact that games aren't 1:1 is because of the software, not because of the hardware.
Wii remote is capable of tracking: Acceleration in all 3 axis. It is capable of tracking rotation on all 3 axis. And is capable of telling depth/position via the sensor bar. Everything you need to track 1:1 if you feel like putting the software processing into it.
PS3 Move is capable of tracking all the same stuff, but it does it differently. Therefore capable of 1:1
X360 Kinect: ditto
Anyways, not all games use the 1:1 capabilities and instead abstract the movements. Most Nintendo games use an aproximation of 1:1 to make things simpler for the user and the programmer.
@original topic
I just watched the video posted on the other page. I'm not impressed by it. Was I impressed by Zelda? I didn't watch the video, so we'll see as time goes on. Lots of games have the same gameplay mechanics as Zelda, that doesn't make them equal.
