Kodak is already in bankruptcy, so killing off pensions may actually be on the table.
Kodak doesn't need to analyze old products to find out what was in them, as they already have all of the files. Also, an Azo replacement is already produced.
Some of the products have changed because some components are no longer available. I've heard tell that Techpan's base material was discontinued, and HIE can't be made on the current coating equipment. (One of the film store guys said that Fuji isn't offering Acros 400 in 120 because one of the component coating chemicals is now banned in Japan because it's too toxic.)
So some things won't be back, ever.
How can Kodak film survive? I honestly don't know the future, because it depends on the consumer base. There are two main film groups: commercial and consumer. Commercial is the motion picture film industry, and consumer is everyone else. Let's say the commercial line dries up because there's a cheap RED 80Mp camera, and all of the big cinemas go to all digital, no film. How much demand is there for the consumer side of film? Is that enough to keep Kodak's coating machines profitable? I doubt it.
I shoot LF, and I don't have the storage space, anywhere at all, to freeze 8x10 film. So when Kodak says goodbye to LF color, that's it for me. There is no Fuji LF color on the local shelves. None. I will get what is in stock at the local shop, and then there will be nothing after that. It will be B&W in LF, unless I build a color seperation camera on my own. Not out of the question, but it also isn't easy.
The Kodak board had some blue-sky thoughts, too, and hired Perez. Sorry, wrong strategy. Kodak invented the boat, and then missed the boat, end of story.
