If Kodak drops film and darkroom supplies because they can't make enough money off of it, I won't miss them (even though I do love Tmax100). I have always felt that Ilford (for BW) and Fuji (for color) seemed more concerned about their customers and quality, at least in modern times. Once upon a time they were a company of photographers, now they're just accounts, and they want to move the last of the 800 Gold.
Kodak is cutting jobs, and moving overseas. Even companies whose product is in demand are doing that. When is the last time anyone bought a Kodak film camera for serious photography? It was probably a Retina. Although I am looking for a Kodak Tourist II w/ super 800 shutter if anyone stumbles across one in a flea market....
As bigger companies drop items from their traditional lines, smaller niche companies are snatching them up, and continuing to market them. I'm excited at the increase in specialized films and darkroom chemicals available from previously boring (you know, they just used to sell the standard Photo 101 supplies) companies such as Freestyle. 35mm, MF, and LF film will still be available for the rest of my lifetime. Maybe not the wide variety of consumer films, but plenty of the pro and art-market stuff will still be popular enough for someone to sell it. If prices get too high, I'll start an old fogies' photo buying club, and we'll buy in bulk.
