There's certainly plenty of room for reasonable doubt that Canon will make anything significant out of their next generation of camera tech, but look at the track record: Fluorite, Electronic AF, IS, Diffractive Optics, 35mm Digital Sensors, 35mm Digital Video, and more recently Dual Pixel AF...
Over the last decade has any other company actually done anything as significant as any of Canon's top achievements? Is Canon just "over the hill" and it's all a downward spiral from here?
I hate to draw comparisons between hobbies because the industries are so different, but look at Nintendo, the company that founded the modern videogame industry when they regained consumer interest after the "videogame crash" of 1983, and they invented most elements of the modern console controller, they invented intuitive controls in a 3D space (Mario 64), then they invented the motion controls that took the world by storm back in 2006, and now they have the fastest selling system in U.S. history (the Switch) because Google and Apple couldn't recognize good gaming if it hit them in the face.
This company has been proclaimed "dead" or "irrelevant" just as often as they've been proclaimed the greatest thing ever to happen to the industry.
Sound familiar?
My argument is relying on some gross generalizations about company culture and progress continuing over long stretches of time, but the two companies rely on similar principals, they're both "user experience" focused and they tend to look for completely new angles on the base concept of their product instead of trying to iterate to the maximum degree.
As far as I'm concerned it's an inevitability that Canon will continue to create new products that catch everyone by surprise and change the industry in unexpected ways.
