As much as I agree with all of your points, asking these questions is simply useless. You're questions are not really questions, but you are just trying to make the same point with every question:
"Look how far behind you are when it comes to video & technical advances compared to your competitors". Don't you see it?"
It is rhetorical. Of course they know. They don't care. And you don't need to ask, you can see it from their current line up and releases. They are focussing on the photo market and gave up to compete on video.
The only question you should ask is: "Why?"
To make more money for a couple of years and then stop the business? A principal? Thinking they will appeal more to photographers if they don't have good video modes? To protect their C-line? (and thus be stupid?)
For the rest I would save my breath. You're not going to change them. But we as buyers will.
