Aside from losing the cinema business, film can't bottom out much more.

To me it seems there are far more photographs in existence presently than in the short/medium term business for film sales potential.

If an irresistable scanner is the way to rebuild film, it should be equally marketed to people who want to share their history, i.e. scan their shoeboxes of photos to share with the world on facebook, dvds etc... Snapshots that are gaining in both sentimental and network effect value.
