I don’t think this is part of what Leica has prepared for Photokina, but this is definitely the first Leica X1 limited edition “Le Mans”:
The Leica X1 limited edition “Le Mans” will sale for €1690 with case or €1590 without a case. A total of 50 pieces will be available. See more pictures @ Leicastoreparis (in English).
There is a picture of a Leica X1 with a silver lens (the original X1 has a black lens) – maybe this is one of the early prototypes?
Few months ago a black Leica X1 showed up on a German TV show.
