From what I've heard, it should be coming to theatres sometime relatively soon - but there's also rumors that Disney is considering doing a "second screen experience," where you can sync up your tablet to the movie and have sing-a-longs and things of that nature... an idea I'm not terribly fond of. Kinda hate the idea of a bunch of tiny screens on while I'm watching a movie on the big screen.
Second screen is cool in your own home, but not so much in public.
