"Canon Announces that everyone has cameras that are good enough and they're going to focus on copiers now. You silly photographers get back to work taking and processing images and stop dwelling on gear."
Sorry, just thinking out loud. In a way, the lack of new models has done us a service, forcing us to realize that we're doing just fine with what we have.
For me, this will probably continue through next year, no matter what they introduce. If others feel this way, Canon may be disappointed with new introductions next year.
From a marketing perspective, I think that derailing the momentum of people's buying patterns is problematic. I'd say that if people expect new cameras, money in hand, and they don't get anything to purchase, that money may very well be spent on other things.
