Will 35mm film ever come back to the mass market?

No it will not and I do not miss it. I prefer to move forward with technical improvements. A visiting speaker surprised the club last year by showing conventional slides. It was not a surprise to me that the shadows were blocked up which is all you can expect for 6-7 stops dynamic range; the photographer had exposed correctly just avoided highlight burn out. Many of our members were not familiar with film and had no idea that the results with slides would be so poor. This does not apply to prints as negative film particularly B&W could achieve much better Dynamic range but nowhere near my current DSLR.

I think it will be there for the enthusiasts, the amateurs and the curious novices. No manufacturer to my knowledge builds en mass 35mm film cameras now. Cross fingers that the old cameras we have will keep working! Mostly for personal use rather than professional. I was talking to a keen amateur (and often winning photographer in her club) who said "I can tell your film images and I tend to like them more than your digital ones." It may be the " look" of film that still pleases the experienced eyes. I used to like the high contrast of Kodak BW400CN now I like the mellow softer FUJIFILM Neopan ISO 400 black and white. As always the choice of film has to correspond to the lighting conditions and the subject. Film processing takes time and since people live in a fast pace they may even resist en mass the appeal of instant film and cameras. Printed pictures have an appeal but can not be evaluated as easily in a global context as digital ones can.

Film prices seem very high for the brands you know.
However, there seem to be some available for reasonable prices: Ilford XP2 (C41 process) still available for under £5.
This site seems to sell a good range.

I think it can be fun, but with the film cameras I've put film it, it's rare for me to actually finish the film and get it developed. And then who knows whether the camera even worked in the first place?

Interesting that XP2 is still available. This is the last B&W film I used about 15 years ago. It was very versatile and, being a C41 process, I could use the same chemicals I used for colour negatives.
I assume that most the interest in film comes from more recent photographers who started on digital. I can understand the curiosity but it is like steam engines; we all like to see and photograph them and even take a short ride. However, if we were faced with say London to Edinburgh by a 1930's steam train now it would not be very attractive being smelly, uncomfortable and slow which more or less describes my experiences of film/print/darkroom. I still think the only future is the curiosity market. Of the 120 members of my club I am only aware of one member still using film though he uses digital most of his photography. I would have thought almost all professionals would have to use digital to survive. The local university still includes film/darkroom in their photography courses but I suspect that this will fade as the current lecturers retire.
