So then will this controller still have the six-axis gyro-type tilt controller technology in them, as well as the vibrate?
That'd actually be really kewl, say for instance in a driving game where you run over some bumps while tilting the controller. The vibrations make your driving less accurate, which is exactly the way it is with the steering wheel.
I agree that it was probably a challenge though, with high frequency vibration and an accelerometer close to each other!? That's just askin for calibration problems all over the place.
