Comment from a reader:
Differences from D3:

1. No red triangle below the second command wheel.

2. The function button appears to be located closer to the vertical grip. On the D3 its higher up.

3. The rubber strap holding the flashsync/remote protection cap appears to be solid instead of two separate straps.

4. It looks like the shape of the timer-lamp is a little different.

5. The shape of the vertical grip looks slightly different (but that could be caused by the angle at which the picture is taken).

But it could just as easily be an older picture of a D3 prototype (instead of a D3x).
