Well, to be honest, Michael's piece was a bit "extremista", so it is only fair for people to reply with polarized and exagerated opinions. If we stick to the facts, and not opinions, camera sales are declining, in all segments, including DSLRs. It is a concern for all camera companies, and I am sure they have inteligente staff looking at the causes and trying to mitigate the trend.
Canon being still number 1 in sales, it is only natural for them to be conservative in their product introduction and development. The fact that they are still number 1, in spite of all the funerals that have been predicted, only attests to the brilliant strike that was the introduction of the EF lens mount and EOS series of cameras all those years ago. Anyone that used a EOS camera, or even a T90 20 or 25 years ago, can pick up a EOS camera today and feel familiar with it instantly. Brilliant design, IMO.
Perhaps the fact that Canon have been under less pressure to change, or to make radical innovations, is due to the fact that to keep being successful, they are the ones that need to change less? All the other companies are trying to carve a place for themselves, or trying to catch up with Canon. And that is the reality.
Of course they can go under and go belly up, but if Canon seriously enters the mirrorless market, they have the potential to make a dent on other mirrorless companies. I think that overall, their approach has been more consisten compared to others. Fujifilm are doing wonderful things in the X system, but eventually they too felt the necessity of making a "DSLR look-alike" XT-1, and will be introducing f2.8 zooms. Why? because they hope that people will buy them in significant numbers, because people still feel that DSLRs are better and "proper" cameras...
