I just came from the theater and a thought hit my mind: People who are not used to computer games do not realize the dramatic difference a faster frame-rate can make.

Once your eyes (and your brain) get used to a reasonably high frame-rate, you are able to spot low frame-rates almost instantly. The old 24 fps frame-rate used by the cinema industry just won't do anymore. Just wait until the camera pans around and you'll realize how bad things get (jumpy movement!).

I think it'll still be some time until we see an improvement in this sector. If you're still not convinced it would be any better, just check one of the fairly common simulators in the theme parks (like "Back to the future"). Those things run at 60-fps, and the visual sensation is something that should not be missed.
