We at TVG have been digging through patents, designs, and trademarks and found something that appears to be an additional weapon in Sony's motion controller arsenal.
Earlier in the year Sony revealed that a sub-controller will be joining the combined PlayStation Move and PS Eye setup. Essentially it works similarly to the Wii's Nunchuk, providing a thumbstick and extra buttons for more traditional controls.
However it seems the overall setup could become a little more complex if the following peripheral designs are anything to go by. Could Sony be adding yet another component to its increasingly elaborate array of motion peripherals?
