Apple profits are also down 26%, it surely means Apple is doomed and iPhones (down 16%) too - even if they don't have a mirror.
They can only survive making more AppleWatch (which sell like mirrorless, more or less), and probably iFridges and iThermos for the IoT madness...
Let's face a couple of things. Economy is still suffering in many areas, including Europe and China. Prices in Europe are "deflating", mostly because people don't buy and vendors try to lure them with discounts. This is evidently impacting sales of a lot of "non-essentials" items, including phones and cameras. I would have been surprised of strong results.
There are surely market changes that will stay - compact cameras will become a niche market, and this trend is being accelerated by phone makers now trying to use picture taking capabilities as a differentiator, for lack of alternative for now. But even the phone market shows sign of saturation - and I wonder how much they can push photo/video features within the form factor and storage/battery size, especially in models without expandable storage and replaceable batteries.
Inkjet printing may follow the same path - as more and more services are available online, less need to print (and scan/fax, but in the company I work for, it looks..). Color laser printers are affordable enough now to become the choice for "heavy printers", but they also last longer too, usually.
Home photo printing will become also a niche for those who prefer to master the art (and sustain the costs) - printer capable to achieve quality results are available, but it's not (and never was) a "you print the button, we do the rest" process - and it's far too easy now to compare a bad print with the original on a portable screen (which could be anyway more contrasted and saturated, and thereby "pleasing" to untrained eyes).
It's clear Canon and others have to realign their product lines, but IMHO the DSLR line is where there are less worries...
