Well you're dismissing things like on the fly color correction, when pre-grading is an important feature for a lot of productions. High FPS is also not a rare requirement. Sports/Action/explosions/water splashing/hair commercials/etc/etc all benefit from high FPS capture. These are all features that the competition advertises. Things like high dynamic range, a file format that allows for easier post production, etc are real tantgible benefits that they give you. I'm not quite understanding where you're coming from.
