Regarding the need for 220 film, there is another option. Some manufacturers, once a year, will make a "run" of film in sizes that are unusual and not normally in great demand. At such time, photographers who use such film in the sizes needed will have an opportunity to purchase the film by pre-ordering, and pre-paying. In such manner, the manufacturer is assured that all the film that is made in a given size is sold and paid for, and the photographer has enough film to use. Obviously the risk is that the photographer will need MORE of the film that was originally ordered, but such risks can be ameliorated if extra film is ordered, and place in a freezer or refrigerator as an emergency supply. I am not sure if Kodak would be open to such a plan, but if enough people committed to buying 220 film, and actually paid for the film when they ordered, then Kodak might be willing to make another run or two of 220 film to see if such a "yearly" run made any sense at all. Of course, the system would only work if those who are upset about the loss of the film actually buy a certain minimum number of rolls. Who knows what such minimum number might be...could be that several hundred rolls would need to be purchased....depends upon the number of buyers, and the minimum run needed to make the film at a reasonable price.
Simply a thought.
