When the 3D movies disappear, is it more reasonable to expect that cinemas will take the cut to their income, or try to raise their 2D ticket prices to make up for the lost extra revenue? I'd expect prices to go up, at least in the formerly-3D theatres that already have the upgraded, premium equipment. In fact, one of the ones nearby does sell tickets to their premium-level theatres for a few extra dollars, even for 2D shows.
