Unfortunately, I feel Fuji is now stuck with E6 film and Kodak may have made the wiser, but unpopular, choice. Kodak produces a small variety of color negative films but Fuji much less so, rather concentrating on the E6 market. Digital has all but eaten reversal film. CN film may have a much longer life due to it's better latitude. Obviously, we would all wish none of the manufacturers had cut anything. I haven't been a slide film shooter for a long time but I don't like to see anyone lose the materials they like.
It seems hard to believe a bottom has not been found by this point. The general public (aka soccer moms) haven't used film in years and even digbibal P&S units have mostly given way to cell phones. Few SM's use anything but phones any longer.
If is wasn't so sad, it's almost humorous to note that 10 to 15 years ago, the silver halide imaging market was at the top of it's game and today so few people really even recall it. This past weekend I spotted my first film camera in the wild in years, other than mine, of course. It was a disposable, but it was film.
