just wanted to point out is that market share does not equal profitability. while there is some general correlation it's weaker than some might think. also, while Canon's market share has certainly slid, it's still proven to be very competitive in the digital camera market, both in terms of compacts and in terms of interchangeable lens cameras. I know I don't constitute a statistical analysis, but I can count on one hand the number of times I've seen someone actually shooting with a mirrorless cam in the past year. in fact, I can count it on two fingers. the number of times I've seen a Canon or Nikon traditional DSLR? innumerable.
I'd love to have a mirrorless cam from Canon as a second camera, to carry around when a lugging a DSLR is unneccesary or inappropriate. however, unless miracles happen in the realm of AF quality and EVF quality, I can't see it replacing my 5DII as my primary shooting camera
