We have known the name “Move” for a little while now and have gotten used to it. The thing is, everyone seems to be referring to the sub-controller / nunchuk by something different... well, no more. Sony has officially put a name on the secondary controller and it will now be known as the
Navigation Controller.
The names makes sense, but isn't that aesthetically pleasing. What about “Nav Stick”? I will probably call it a nunchuk.
Engadget discovered the name in Sony's FCC filing for the device and offered an image from the filing showing the label for the controller.
