Well considering that list was updated in May of this year, I'm going to assume it is correct in saying more than two IMAX theatres have film projectors. And apparently the one I go to (Lincolnshire) does still have 15/70, oddly enough I haven't seen them use the 15/70 film projector they supposedly have each time I've been there.

Hopefully, they'll use it for Episode VII. Personally I really want to my first experience of this movies to be without me having seen the trailers, and with a real projector, but I'm not sure if either of those goals are happening.

On another note, does anyone know of a list for 35mm film theatres?
