I speculate that there is latent demand for it between older people that miss it and younger people that are tired of pure digital and want something more organic and different.

Which I actually sort of appreciate (in my less cynical moments). Though, if it's just that they've never shot anything on film, I'm sure they have friends or co-workers with old still cameras gathering dust. Borrow one, shoot a roll of film, send it off to be processed, and the urge will probably have gone away by the time you get your prints back. You can get those prints scanned too if you like.
Personally though, I would rather have something similar to analog that doesn't require the cost and time/complexity. I wonder how many folks will buy these to go with them: http://nofilmschool.com/2013/12/nolab-digital-super-8-cartri...
