I've searched ps3news for this bit of mouse controller and couldnt find it, so im posting it here. The right-handed mouse controller has a complete set of PS3 buttons, and will bring PC-style shooting to the PS3.
Peripheral maker SplitFish today unveiled the upcoming FragFX game controller for the PS3. The device features a seperate right handed mouse and detachable left handed grip controller, ideal for experiencing traditional PC mouse and keyboard style gameplay in shooters.
The mouse is also optimized for navigation in the recently announced PlayStation Home virtual world. A menu mode on the mouse allows it to double as a regular mouse during menu selections. A lap mouse pad and left hand grip cradle is included with the FragFX to allow for comfortable play in a living room setting.
