I highly doubt the actual connection is through the hotshoe- after all, the contacts are purely electrical, right?

Not quite. The 2 extra pins at the rear of the hotshoe are only power pins, used on the NX200 to supply power to the SEF8A flash. They may be included on the NX20 so that the same flash can be used. However there is little need for that since the NX20 has a built-in flash, so I suspect they are intended to also power other devices via the hotshoe. For example, the current GPS10 gps module requires 2 AAA batteries. They could make a much smaller gps module by eliminating the batteries.

There are also 4 data pins surrounding the central pin of the hotshoe. At least a couple of those are superfluous for flash purposes and are already used for routing gps data to the camera when the gps module is in place. There's no reason they can't be used for other purposes, as they apparently are for the stereo mike.

Anyway, as has been said, I doubt they would put a jack in on the nX210 and not on the NX20.

Agreed.
