So you know where I'm coming from, I'm a filmmaker and producer but I've also worked in advertising and tech. I follow tech developments quite closely, especially Apple and camera news.
In my opinion --
Canon cannot afford to be afraid to protect their higher end markets anymore. Sure, they produce amazing EOS still and EOS cinema bodies but they can't worry about cannibilization anymore. Canon makes GREAT products. Professionals will continue to buy 1D-Xs and C500s even if they sell the same autofocus points in a 7D or a Rebel, or enable RAW video in a 70D.
Canon has high-end lenses, both still and cinema/video, that professionals will continue to buy no matter what. Canon has tons of patents and will continue to innovate. It just has to have the confidence to not worry about those who will stop buying their high-end products.
Give people what they want- give them RAW video at an affordable price (yet with a healthy profit margin). Apple successfully cannibalizes itself over and over and over. Jobs said it best when he said (and I paraphrase) sell low and go for volume.
Oh, and in case you're listening, Canon, yes -- I do want you to OFFICIALLY enable RAW in the 5DIII and 1DC and sell them for less. Don't worry, we'll buy more of them.
