>24fps has long been the standard for "as smooth as real life" motion in the movie & TV industries. Which is fine only for non-action scenes, and film also has motion blur to make movement look smoother. Action scenes in games (especially without pseudo motion blur) look significantly better at higher than 30 fps. 24 fps was also chosen as "the minimum we can get away with", so I see no reason not to increase it when you don't have to pay for film stock.
