With rumours abounding about the possible name of Sony's motion controller, the company will finally unveil it during next week's Game Developers Conference.

Sony will be debuting the final product next week at a private event held off-site from the official Game Developers Conference. According to my sources, the official name of the PS3 motion controller will be revealed.

Siliconera reports that has registered "PlayStation Arc" as a trademark in Japan, which makes it the likeliest candidate. Some employees of the company have even been caught referring to the controller by that name.

Whatever it's called, Sony has promised to release the controller this autumn.
