Exactly. It's not that the newer resolution technology is getting in the way of creating stills, the style between the disciplines is the bigger issue. Personally, I foresee "still-lifting" as a supplemental tool. Useful when appropriate.
The way I shoot documentary montage sequences doesn't lend itself to great photos, but the way I film certainly works in the editing booth.
I also agree that someone will create a hybrid style that does do both at the same time and will do it very well. It'll happen sooner rather than later.
