I think canon since the 50D has become overly influenced by accountants than photographers.
Does anyone actually think it was the 'photographers' idea to merge the 1D & 1Ds line. Of course not, it was a business decision to take two lines into one. Although 1 series cameras are the flagship and what people read about in magazines, and good for marketing, they are not the money maker to canon. Why tool two assembly lines when you can tool one, and charge more to help with the R&D costs. Hence "we merged the camera lines to one super duper camera!" Ta-Da!!!!
At the end of the day canon sells Rebels through to 5D's to make money and 1 series probably cover costs because of lower production runs and make for good advertising. Average consumers ogle 14 fps, they don't read that the it is achieved with mirror lock. Rebel owners don't ogle over f8 focusing etc.
But at the end of the day we need consumers to buy lots of consumer grade cameras so the R&D can continue to build 1 series cameras for the pros and serious camera enthusiasts. In the meantime we take a hit during economic deprived times where companies are most interested in staying afloat, which doesn't put them in a spot to cater to specified groups that don't have the camera sales to justify another line.
At the end of the day make as many product lines that are financially feasible and target the biggest markets. They are corporate company and have to focus on the bottom line.
Sucks at times but that is business.
