Missed this announcement at Photokina (saw it mentioned at the Nikon D600 Club).
That USB Dock looks interesting. Too bad it appears to work only with newer lenses. The old lenses -- the ones that are in most need of firmware updating -- don't seem to be compatible with the USB dock. Unfortunately for my Sigma 50 1.4 and Sigma 50-150, both of which don't focus in LiveView with the D600. argh.
