From LeicaRumors:
Do you remember the Leica M11 launch video that potentially identified several upcoming Leica cameras? It seems that there is another possible easter egg in this particular video (or maybe just another regular prototype?): the scene with Mike Shipard also showed what looks like a Leica S mirrorless medium format camera mock-up placed on the table together with other prototypes. This is at the 2:08 mark of the video, just after he walks off-screen, the third camera back – what do you think?
