The controller? Is that why Kutaragi has not yet let anyone else even hold his joystick? What secrets could it possibly have?
My prediction: The DualShock3 and EyeToy2 work together, the controller has some leds or even just some "glow in the dark" markers in front (the side facing your screen), possibly 4 pieces in a diamond formation, that the EyeToy2 can easily "read" even in dark, so as well as using the traditional buttons, you could control by tilting and moving the whole controller around. The leds would just add precision to the "motion capture" and the controller would have exactly the same functionality as the Revolution controller, maybe even more, and it would not really add to the cost other than the new Eye Toy2.
Of course the EyeToy2 would work without the controller too, but working in tandem with the DS3 would open up more control options in traditional games too, not just controlling wawing your hands etc.

Should I sue them, or just settle for a free PS3 for compensation.The controller uses four LEDs to capture this motion, but in a twist from Nintendo's sensor bar configuration, the LEDs are mounted on the controller itself. A camera mounted next to the player's television set takes many pictures of the four LEDs every second, and this data is used to calculate the position and velocity of the controller.
