I have it straight from the horse’s mouth (StarWars.com). Episode II will be shown on IMAX theaters around the US and Canada starting November 1st. The news release has some interesting info about the transfer process, but no mention of what theaters will be getting the film.

My guess is if your town got either Fantasia 2000 or the rerelease of Beauty and the Beast, you’ve got a good shot on getting Episode II as well.
