The silver Zeiss Ikon film rangefinder camera has been discontinued according to Cosina Japan website. Last year Zeiss discontinued the Ikon SW (Super Wide) version that did not have a viewfinder/rangefinder. The black Zeiss Ikon rangefinder camera ($1,618.00) is still available for sale.
Zeiss has mentioned on several occasions that they do not have any plans for a digital rangefinder camera. They should. The Leica M9 remains the only full frame digital mirrorless camera out there and it seems that none of the camera manufacturers has the guts to go full frame. At one point I really thought that Fuji will be the first with the X-Pro1, but even they didn't do it. In the mean time, Leica will probably announce a new full frame rangefinder (M10?) this year at Photokina and will sell every single piece they produce for the next two years.
