Found this very interesting. There is enough rumors going around that I'm sure Sony is working on something...as they say, every rumor has a nugget of truth buried in it....Sound like you have some type of sensor on each hand and foot...to mimic actual body movement.
I don't know what they're working on, but we'll probably hear something at E3.

Rumor: Details On Sony's Motion Controls, No "Break-Apart"
An anonymous industry source has told Kotaku that reports of a "break-apart" motion controller for the PlayStation 3 that splits into two parts are not entirely accurate.
The control system, said the source, actually consists of a smaller-sized device that can attach to the body - and multiple devices are intended to be used in concert, such as wearing two on the hands to move a character's hands in-game, or four, on hands and feet at the same time to move a character's body.
Though the source admits the technology might have evolved since the last time it was seen, the source disputes the idea that any of these pieces merge to form a single controller. It is also unclear how the individual pieces will be packaged, whether individually or in sets.
Sony declined to comment on "speculation."
