...My point is that the past is usually a good indicator to the future. Canon likes to recycle its tech for generations. Nikon, Fuji, etc., have surged ahead with their APS-C cameras...
This statement doesn't seem to have much relationship to reality. In which generation of XXD cameras did Canon recycle its tech? 20D to 30D I guess, but certainly not the 30D to 40D, 40D to 50D, or 50D to 60D. How about XD cameras? I can't find any 1D or 5D generation that shared the same sensor tech as the previous generation. Are you aware of one?
How exactly have Nikon, Fuji etc. "surged ahead" with their APS-C cameras? Nikon seems to be cramming more megapixels into the sensors they are using, but it comes at a price in noise at higher ISOs. Canon's nearly four-year-old 18mp sensor still competes very well. Fuji is doing some interesting things, but again, we are talking marginal improvements rather than surging ahead.
A more accurate statement would be that after nearly four years, competitors have finally started to catch up to Canon.
