The sad thing is that the film is not only discontinued in small sizes but also in 16 & 35mm and that at time were Fujifilm killed their MP-Lineup. So basically it's bye bye to Color Reversal film in the pro motion picture market.
Nobody should blame Kodak after all Fuji gave the MP-Film world a big F**ck you a few months ago and Kodak still offers Super 8 and other Films.
