I'm new to this discussion, sorry if the following points have been made before.
1. Film cameras were - completely - obsoleted by digital cameras, except for the dedicated (and anachronistic) hobbyist. It started with the midrange of the film camera market (okay quality point and shoots), moved to the low end (cheap point and shoots) and the high end (SLRs, high end rangefinder).
2. Digital cameras are now being - partially - obsoleted by smartphones. Very few people carry a digital point and shoot camera, they simply take pictures with their smartphones, and this is especially true of younger people. With smartphones becoming almost universal and less expensive, the digital point and shoot camera will disappear.
3. Digital cameras were able to completely replace film cameras, because they could do everything that film cameras could, and were so much faster, cheaper and more convenient.
4. Smartphones can only
partially replace film cameras, because they are inherently limited by the tiny sensor and tiny lens. Smartphone pictures are just fine for most people and most purposes, but there are people and purposes that only a camera can satisfy. (Among those "purposes" are to show off, to be a toy, etc - it isn't all about function.)
5. So in a few years, on the CIPA chart almost all of the "compact digital" bar segment will have disappeared. There will be the "D-SLR" and "mirrorless" bar segments, and maybe a new bar segment for "action camera" or something else. The total bar will be maybe half the height of the 2014 bar. Yes, digital camera industry production will be cut by another 50% or more.
6. How terrible is that? Well, look at the bar for 1998, the peak of film camera production. The great majority of that year's production was point and shoots, mostly pretty cheap ones. Maybe 25% of the bar represents quality, interesting film cameras - the higher end rangefinders, the SLRs, the MFs etc.
7. Take the 2014 bar, cut it by 50%, and - hey - that is pretty close to taking the 1998 bar and cutting it by 75%.
In other words, the higher end digital camera industry will be about the same size (in units) as the higher end film camera industry was before. The lower-end and mid-range digital camera industry will largely disappear.
8. So, in a nutshell, my prediction is:
a) The
digital camera will consolidate to only DLSR, mirrorless, high end fixed lens, and any other form factors that cannot be replaced by a smartphone.
By units, the industry will lose 50% of its current size, but it will probably lose only about 25% of its revenue. Because the digital point and shoots, that are going away, are lower end and lower price. For example, in 2013 the industry made about 44 million digital camera
units with fixed lenses and about 16 million with interchangeable lenses, but the industry's camera
revenue was about JPY 550 billion from fixed lense cameras and about JPY 650 billion from interchangeable lens cameras.

b) Some companies will be driven out of the business, most of the major brands will survive. For example, Nikon's imaging (camera) business made revenue of JPY 352 billion and profit of JPY 31 billion in 1H2014, it made revenue of JPY 277 billion and profit of JPY 27.5 billon in 1H15, when the "compact DSC" (as they call the fixed lens category) business goes entirely away, Nikon's imaging business can probably still be profitable. Admittedly ownsizing will be required - won't need as many Chinese assembly plants, etc.
