I understand. If Disney gets it, I'm afraid they will sit on it and barely do enough.. like "star tours". I am hoping Uni gets it, due to their excellent handling of Potter (from most reports- have not been there yet myself). Also, Disney has years of Avatar to finish- we all know they can't handle 2 projects at once.. which means it wouldn't happen until 2020 at least!
I also just don't see the Tolkiens handing it over to Disney, that's why I don't buy the "rumors". I'd love to know the sources, but I don't think it's anymore than "what-if" wishes at this point.
