Film prints may be dead, but some directors are still going to shoot in 35mm.
If the bulk of currently installed digital projectors can't handle 48fps, or be inexpensively upgraded, it's going to be a while before more people can see movies shot this way.
I am cautiously impressed with this new technology, but still don't think every genre would benefit from it. And I hope we're spared some sort of bad conversion of older films as a cash grab, that will ruin it for everyone.
