Such a shame that one of the best themed queues in theme park history is going to be changed. Of all the work that IOA needs, I don't think that changing the theme of DD should have been anywhere near the top of the list. But they are pretty desperate right now and Potter is really the biggest thing they have ever done. If this is a hit, they can take a nice chunk away from Disney, especially with European guests. But if the reaction to Potter is subpar, who knows what will happen to the resort.
I personally dont see how tthis will take a "huge chunk" from Disney. I travel thousands of miles each year over from the U.K. and never spend more than a day in each of the Universal parks even with HP this may not increase the amount of time spent there drasticaly (even though the dw is a Potter fan).
Can't see the mouse being overly worried about this new land because it will just draw more bodies down to Florida and more bodies in the area means more for all the parks not just the original destination.
Competition is a good thing and only serves to better the experience for u all...
