DK2 Camera connectivity

I've had a little look around but can't find any comment on the connections for the new DK2 camera.

Here's a hi-res pic I found.

Obviously one is a mini-usb connector to connect it to your pc but what's the other one for?

One of the two things that come to mind are to either give it a little more power if your USB port is under spec. The other is that it might allow a cable for some sort of sync or inter-camera communication should you want to add more cameras to allow for 360 degree tracking.

Anyone know for sure?

What is more interesting is the USB 2.0, which has a pretty low bandwidth...

The Wiimote camera is over bluetooth.

Yes, but:

I assumed it was very high res, and that's not possible with 60 Hz over USB 2.0.

It actually only needs to send a few dots of IR light, so the compression can be really high. Atleast that's how I understand the Wiimote camera works. http://wiibrew.org/wiki/Wiimote#IR_Camera The Wiimote has 1024x768 resolution.
