In the mean time I am shooting great photos and avoiding making sweeping generalizations about my peers.
Well, I did try to limit the generalization a little and of course it's just my 2ct personal opinion in a rumors forum. No doubt you can take great shots with a 5d3, 60d (my current camera) or 6d (my next camera). But imho it's like with all tech advancement, people on the older/current tech often seem to like to stick to the status quo, like b/w->color tv, horse carts->motor cars - you seem to be an exception to the rule if you say you'd like to have d800 specs.
At bottom, a super wide DR gives one a RAW that looks dreadfully flat not gloriously beautiful.
As long as the bit depth rises to 16bit, I don't see any problems with higher dr sensors - dropping data is easy, adding it after highlights are blown and shadows are noisy is another matter :-o
Why you need new Canon sensors like every year? If they pump out something awesome every 5 years im down with that. Would be crap if my new FF purchase would be blown away by next years release.
That's just it - the current Canon sensor tech is 5 years old (5d2-gen, recycled in 5d3/6d) - Canon is bound to make a big leap this or at least next year, if not for the sake of tech advancement then to keep up with the competition. The 1dx sensor with might be the first indication, it has other tech as the iso->dr curve shows.
