According to the above, they've deep-sixed a total of 7 films in the US market: Fujicolor 100, Reala 100, Sensia 200, Sensia 400, 160S, 160C, and 800Z. (9 if you count CDU II and Nexia 200.) T64 and Neopan 400 are supposedly on their way out, too. But they're both still listed and available as of now. Reala supposedly continues in Europe (?).
Well, that's really horrible news. Guess I'd better stock up while I can and start switching to other sources for the future.
