I think you'll be far more likely to see a split, in the same way today we have films shot in CinemaScope (2.35:1) and widescreen (1.85:1). The complement, rather than replace, one another. 48 FPS is probably analogous to 3D, rather than talkies. When the talkies came along there was a rapid transition: the big five studios were exclusively shooting talkies about two years after the Jazz Singer was released. Whereas 3D is more prevalent today, but some film-makers choose not to use it. There is not quite the same demand by the audience. I mentioned this earlier, but I'd love to see a screening of The Hobbit with 24fps for dialog and 48fps for action.
