Canon has lost this generation of camera bodys. So what? Nikon had been living in canons shadow since the d30. 
I would have said Nikon had been living in Canon's shadow since the first ring type USM lenses.
Sony/NIkon have kept going up in the past decade while canon wanes.
Really? 10 years ago Sony's camera division didn't do SLR's. Konica Minolta did and they were nearly dead.
Up until the D3x, the D800 and the D3200 Canon had the march on Nikon at every price point regarding MP, and usually feature set.
And if what we've seen from sony and nikon continues, canon is going to have to earn its customers. something which they seem honestly not used to doing.
Are folk jumping to Sony DSLR's? most of the talk I hear is of folk hating the SLT finders. Before Sonys most recent range their DSLR's were usually plagued with horrible noise from moderate ISO's. Perhaps the mirrorless segment is where they are gaining ground, a segment lets not forget, where Canon are not yet present.
Just about the last thing canon should do is stick their head in the sand and keep believing they are too big to fail.
Don't get hung up on bodies so much, look at Canons lens range. Loads of new versions and even completely new lenses in the last 3 years, from TSE's to pancakes, to super telephoto L's. All that resolution is only as good as the lens in front of it...
Who knows what Canon have in the pipeline? The 5D2 is still a brilliant camera at a briliant price. The 5D3 may not have been the leap that pixel peepers wanted, especially in the shadow cast by the D800, but then, they are clearly different tools for different jobs.
If what you are using is working for you then keep using it if you aren't happy with the current offerings.
I remember when Canon launched the c300 with some fanfare and all the canon knockers were scoffing because the 4k red was launched the same day. A year down the line it's quite apparent that canon have had the last laugh. The c300 is a go-to bit of kit. Folk realised that 4k isn't necessarily better for every type of job.
Maybe folk need to start realising that 36MP isn't necessarily better, or that the D800 isn't necessarily the best camera for every job.
