I've been to a few local camera shows at a local chain's home store. Everything available in the USA is there from pocketable poimnt and shoots to the premium fixed lens cameras, ILC's, consumer DSLRs and Pro DSLRs. If you stand around and listen you get some clues. Everybody wants to try the latest ILC's; but as soon as a larger lens is mounted, the atendees all say pretty much the same thing. "by the time you add a decent lens, the value of the small body is lost" Adding a Sony G series 70-210 f/2.8 to a NEX7 with the adapter got a lot of laughs.
The truth of the situation is that the lenses are too big for the bodies. All the media hype has been about how small the body is. That might work for a fixed lens compact; but as soon as you add a zoom lens with some reach, the hype is seen to be just that. The size, balance with larger lenses, and quality of the smaller DSLRs is also a factor.
A further factor is just how good the better fixed lens compacts have gotten. And a lot of those close up to a jacket pocketable size with better image quality than most buyers really need. I'm speaking here about cameras like the G15, XZ2, ZX7, RX100, and so forth.
Something that the manufacturers need to come to grips with is that people really don't want to change lenses and carry a bag with several lenses. Development of lenses like the 18-200, 18-250, and 18-270 is evidence of this. On my 60D, my main lens was the 18-135 IS. On the D90 it was the Nikkor 18-200VR. Both set ups weighed around 1350 grams or 48 oz., and there was also a bag with accessories and lenses. Both cameras got replaced by a G15 and an FZ200.
I know it's egocentric; but I really do think that my views are typical of the majority of US buyers out there.
I also think the argument that ILC's are not selling because they are not stocked is a false argument. Rather, I think they are not displayed; because they don't sell.
