I don't know how this might affect our film supply, but according to my friends who work in the movie business there is still a large amount of work shot on film, I don't think one can say as yet that most films are shot digitally. There are many directors who aren't yet sold. Digital projection is also another threat, and for me just one more reason to stay home and watch movies there. What's the difference besides an over-sharpened image and over-amplified sound? Oh and rude people who won't stop talking behind you. No thanks to that and 3D.
