Disney has also been trying to get rights to other studios' big movie franchises...they failed with HP....and wasn't the rumor that they were trying to get LotR, but that wasn't going anywhere either? I think, and this is pure speculation, some time down the line if they can't get any of the other big franchises in the park they'll probably bring some kind of PotC attraction (stunt show?) as well as a Narnia attraction (if the movies keep making money)...
I think the name change is a good thing...now if we can get them to gut the movie ride and get something completely new in there....I'd be happy. :lookaroun
If HP is a success at Universal, I think Disney will look to counter that at DHS. Would be real nice, if Disney can seal up a TV deal for Lucas' Star Wars tv show...and open it up for a LucasLand at DHS or something.
