it is very simple. Canon and Nikon are being punished for not having brought to market DSLRs that are both affordable and interesting to regular-income photo enthusiasts. Lack of interesting products ... less sales. 1 Million less incrementally boring DSLR-iterations ... hahaha, I love it. Customers are king, after all.
Two years ago (late 2012) Canon and Nikon missed the boat. No compelling and affordable APS-C DSLRs. No D400. No 7D II. Pricing closer to USD 1000 than to 2000. Of course with built- in GPS, Wifi, and in Canon's case EX-RT radio flash trigger. And fully articulated LCD (not just tilt!). For Canon the old 45-point 1 AF system plus a kick-ass 24MP APS-C sensor, half a notch better DR and Hi-ISO than the Nikon D7100 sensor. Nikon would have easily gotten away with the D7100 sensor and AF system (Multicam 3500DX).
And today, CaNikon are missing the boat again, because they have no mirrorless FF MILCs ready now and it looks they will not even have one ready within the year.
These days, only a few budget-restricted, conservative die-hards insisting on OVF are willing to swallow marketing-crippled FF DSLRs (6D, D610) still priced at more than 1500. All others are buying Fuji APS-C instead and/or are will be buying innovative and more affordable FF-mirrorless cams.
CaNikon are in for a lot of punishment. Well deserved.
Punished??? The whole market is down! It is the economy that is under tremendous punishment which is translating into lower sales of consumer goods.
Just because you need EVF and mirrorless doesn't necessary mean everyone wants them. BTW, how much profit did the fan favorite Sony with its EVF and high DR churn out???
Additionally, late 2012 was last year ... not two years ago
