Unless someone here has access to the sales figures of at least the big three makers then anything else is anecdotal evidence based on press reports or their own experience. The latter may be interesting to read but isn't enlightening on deciding the answer to the question.
I get around a number of places that attract photographers such as tourist areas in Cornwall and what in the U.K. is called National Trust properties. I am still waiting to see another film user anywhere although I make it my business to check out what kind of cameras users have.
Clearly my experience can't be representative but until I see sales figures I don't know how I or anyone here can reach any meaningful conclusions.
