From now on, frame rate will be just like aspect ratio: another choice for the filmmaker. Some movies will still be in 24fps, some will be 48fps (or some other value), and eventually some will probably be variable from scene to scene.

As for the Hobbit, I think HFR could certainly have used a better "ambassador" film. Maybe James Cameron (who has also talked about 48fps from time to time) will do a better job of it in his next movie.

I'm guessing you'll only see 48Khz employed for recordings of real events, like musical performances, that Cirque de Soleil film they're pushing just now, and lavish documentaries in exotic locations such as nature films.
