The XBox 360 controller indicates that FFXIII is on both the PS3 and XBox 360.
There is a third party PS3 controller which is very similar to the XBox 360 controller. "PS3 Extreme" has all the functionality of the PS3 controller including rumble but no Six Axis support which is rarely used in PS3 games. "PS3 Extreme" retails for around half the price of the expensive PS3 Dual Shock 3 controller.
