Ok there's
Natal-motion sensor that looks stupid, I mean this thing would require major tweaks to work for just one game. And I would just as soon have the controller, because with a controller there is a physical response

Wii motion plus- I was interested by a movement based system that still had a controller. The motion plus is an enhancement that from what I can tell nearly double the sensitivity of the movements

And Sony's new wand thing... which is exactly the same as a Wii mote, my bitching aside I hate this. This is their biggest insult to Nintendo since they bought Final Fantasy... although to be fair square enix's last 4 FF were shit.
