Dueling Dragons is being rethemed to the Triwizard Cup Tournament and the Flying Unicorn is being rethemed to Hagrid's Hyppogryph (sp).
But (it's funny how Disney fans are ignoring this aspect of it) Universal is also building a fully explorable recreation of Hoggwarts Castle and a new "E Ticket" attraction utilizing Kuka Robocoaster technology (the stuff Disney wanted for an Incredibles attraction) rumored to be themed off of the flying car from Chamber of Secrets. Also, a recent article posted on Themeparkinsider had a Universal chef discussing some of the things they were developing for the new resturaunts... to include Butterbeer.
Furthermore, they have the set designers from the movies working with the parks to ensure consistancy between the film and the new attractions.
And one more person calls the Wizarding World of Harry Potter "PotterLand" or "PotterWorld" I'm going to virtually shoot them before calling Frontierland, "Cowboy Town" and the World Showcase "Snooze-ville."
Well I think I've found the spokesperson for Potterland...er, the "Wizarding World of Harry Potter(tm)."
Just kidding
