A hoax. Nothing to see here. Move along, move along.
Turns out, Gianluca (janlu) posted a 5D Mark II photo as a Leica M photo.
Original story: User "janlu" posted the first sample photo we've seen from the new M (at a decent size anyway) which illustrates something we're all probably wondering - the maximum ISO of 6,400. It was shot using the Summicron-M 28mm ASPH, 1/80s @ f/2, using AWB - JPEG directly from converted DNG without post-processing.
