Mad Catz are well known in the gaming industry for making some great peripherals. There was even talks of a law suit sometime ago versus Microsoft for the controller being to similar to the Xbox 360 one.
Now the peripheral maker has teamed up with Activision to create a series of special Call of Duty branded controllers called “Black Ops PrecisionAIM controllers”. The most noticable feature cosmetically is that it looks like a perfect cross between the PS3 and Xbox 360 counterparts. The analogue sticks are in the position of the PS3 ones but the overall shape is that of the 360.
I think you will need to import the controller should you want one. They will be available from November at a cost of $50.
