I have become very impressed with the photo taking abilities of small phone cameras. Particularly very good phone cameras, like my buddy's Apple.
I think the modern phone camera, especially the top of the line version has become a threat to regular cameras, such as DSLR's, mirror less, 4/3rds, etc.
IMO competition has become really big (DSLR), sort of big (mirrorless, 4/3) VS ever improving phone cameras.
I'm seeing a lot more people using their phone cameras every year. I've seen some 8 X 10's developed from phone cameras and you know, even for a pixel peeper, like ' yours truly', I have to admit, some of the better phone cameras can produce really good photographs and print at 5 X 7, up to 8 X 10.
In fact, when I think of it, with my DSLR, I rarely print over 8 X 10, mostly 5 X 7, rarely 11 X 14.
When I looked at a buddy's 8 X 10 B/W , compared to other B/W 8 X 10's he took with his mid level DSLR....I have to really strain to see any difference.
My prediction. Drum roll please...the envelope.
Within 5-10 years through ever improving technological evolution of small camera phones ...I would be surprised if many carried a DSLR, mirrorless, 4/3rds, point + shoot and a kit of lenses. There will be a few diehards still using larger cameras, but there numbers will continue to dwindle.
I could be wrong, but I don't think so. Some may say, but technology will also increase with larger cameras....which might be. But if you can get excellent enlargements ( 8 X 10, 11 X 14) of similar quality that a DSLR can now (2014) produce with a small, convenient phone camera....why would even an enthusiast want to lug around a large camera with a kit of lenses ?
