GamesIndustry is reporting that Sony Computer Entertainment is at work on a new PlayStation 3 controller which will "break apart" into two individual units, each containing an accelerometer for Wii Remote-like motion-sensing functionality.

According to unspecified sources, working units have been delivered to development partners, although it's not clear when the pad will be officially unveiled. As expected, Sony Computer Entertainment declined to comment.

A differing report at Kotaku, however, suggests that the control system consists of a small device that attaches in the body. Multiple devices can be worn, such as two on the hands to move a character's hands in-game or four on the hands and feet. Kotaku's source disputed the notion that the pieces would merge into a single controller.

At present, the PlayStation 3's Sixaxis controller allows for basic motion-sensing functionality, though not quite as articulated as what's offered by Nintendo's Wii Remote and nunchuck controller combo.

The runaway success of Nintendo's Wii console has led many to speculate as to its competitors plans to break into the motion-sensing sphere of gaming. Last April, rumors circulated of a Wii Remote-like peripheral for Microsoft's Xbox 360, codenamed Newton, reportedly aimed for debut the following month. No official announcements for Newton materialized at Microsoft's product showcases.

Should Microsoft or Sony indeed be working on controllers or peripherals to counter the Wii, those products—such as the above-mentioned PS3 "break apart" pad—will likely be unveiled at this year's E3 Media and Business Summit.
