We have all commented on how Fuji has a very large share of the E6 market while Kodak has a large share of the C41 market. This is mainly due to the fact that Kodak has the largest share of the motion picture market. As a result, The Vision films support the C41 films, but with Fuji, all films are more or less stand alone and move directly with their respective markets.
If E6 vanishes, then we are faced with a huge loss to Fuji and a comparatively minor loss to Kodak. That is the way I see it. It remains to be seen whether Fuji can withstand the shock, but it seems as if they and Kodak are preparing for what is to come.
E6 has been hit hardest by the digital revolution. What happens will happen.
