I still believe that SW-Land should have been the WDW counterstrike against Universals WWoHP, not Avatarland. With the exception of perhaps Lord of the Rings only SW has an even larger cult following than HP and SW is an ACTIVE franchise, three more episodes ahead and at least two TV series. Yes I know, there are sequels planned for Avatar as well (And Cameron is the master of the sequel, Aliens and T2 prove it) but so far Avatar is just a single, VERY successful movie but with NO cult around it what so ever. It still has to prove, if it is more than a megablockbuster that people watch and are impressed by but then go on with their lives without any influence by the movie. Star Wars changed a lot of lives! And SW-Land would be much better to deal with Harry Potter because it produced already and guarantees an entire galaxy of possible merchandise. Honestly, how many Avatar related toys exist? Not even Lego, who today really sadly produce any BS as a merchandise product so far features Avatar sets (the Lego Avatar has nothing to do with Camerons movie!) And how many children play with Avatar toys and how many SW toys do they play with?
The coming expansion of WWoHP in the US (London and Diagon Alley) and the Hogwarts Express look impressive! Together with the already existing Hogwarts in the UOA this will be a real challenge for WDW. I don't know if Avatar, let it be as impressive as hell, is really the adequate response. Many people need a connection to a movie related attraction to be thrilled by it. When they announced the building of Cars Land in DCA I couldn't care less, I didn't know the movie, I wasn't interested. Later, after I saw the movie and became a Cars fan, I adored the idea and when it opened, I knew I MUST get there in the next two or three years, this fall I will finally be there (I hope). Many people have seen Avatar, yes, but MUCH more and that over an entire generation have seen the SW movies. It's an integral part of the western pop culture of the 21st. century. referenced in numerous movies, TV series etc. Avatar has so far not even remotely the same influence. Even if Avatar-Land is a blast (and it really could be one) it will not be able to top the possible attractiveness of a fully developed SW Land.
