I think analogue in general is seeing a resurgence, for a number of reasons. Most major metropolitan areas have record stores that have quite a few young patrons. I can only assume film photography merchants would see a similar rise. Before leaving Tokyo, I found closet-sized shop in an unassuming neighborhood which had a handful of things I wanted. Not only that, but the owner was quite knowledgable and fun to talk to. He said a surprising number of people that come and buy European film from him was surprisingly high. Many that shouldn't "remember" what taking analogue photos was like. Sadly, he was the only brick & mortar in a city of 30 million or so that sold Rodinal. :-/
I don't think we're going to see the big dogs bring back their dead lines (so long, E6), but I believe we'll see some longevity in the medium, and if someone can figure out how to make it worthwhile to produce in relatively small numbers, even better. Again, look at the vinyl record market. There's plenty of labels putting out vinyl that weren't 10 years ago. Some micro labels have figured out to at least break even on runs as low as 300.
