The revival house near me is literally a one man operation that only exists by the good graces of the dollar theater that hosts screenings. (Thankfully, they just posted their schedule through September.) Even if a theater keeps it's old projectors in place, this could nail the coffin shut. :(
I don't get out to the movies as much as I used to, but I haven't seen an actual film print for a first run movie since January 2011, and that was out of town.
