What do you know... Nikon finally beat Canon in doing something.
I don't believe their comment about it being profitable. If it was, they would keep making at least some of the products. *I suspect that Nikon hasn't been making most of these non-camera body items for some time, just putting their name on them.
Based on what has been going on in the camera world in the last few years, I suspect this is not as big a deal with Nikon as it might sound. They have probably been cutting back and shifting products for the last several years based on the decreasing use of film cameras, film and darkroom equipment.
