One of my VERY best friends is a Leica Guy. I know people say these Leica guys are stuck up, and hung up on gear but not my good friend. He's a photographer. Has taken, dropped, had repaired, shot, got wet, etc EVERY one of his six Leica bodies - including the Monochrome. The Leica store in NYC LOVE him. He walked in last year for a Leica branded polarizer, and walked with their only cop of of a think a 90mm lens that had just come out. It was five figures deep that one~. He also has several 80 megapixel + higher Hassy medium formats with some serious glass. Last Christmas he bought for each of his three sons a new Leica body and a 50mm Summicron (?) lens! Like I said - BIG BUCKS. He just. bought the 60 megapixel S2 MF Leica as well a few months ago - And guess what? He actually ENVIES my fuji 50r and my APC cameras! He truly loves them but I think he's afraid of switching at this point.
Long story short, I do believe that FUJI will be out with a medium format Monochrome by next summer or fall. If they do, I and my friend will be first in line!
