Harry Potter doesn't have a whole theme park dedicated to the franchise and that means Star Wars shouldn't either. Harry Potter only has an area, not a whole theme park. That is a big difference. Star Wars having a Land should have no problem, but an entire park is out of the question based on how Universal is handling Harry Potter. Now granted Harry Potter was responsible that big increase IOA has for attendance, but his land is only one part of IOA despite the impression people have with IOA.
IOA has Port of Entry, Marvel Super Hero island, Toon Lagoon, Jurassic Park, The Wizard World of Harry Potter, The Lost Continent, and Seuss Landing.
Universal Studios Florida also doesn't have a whole Theme Park dedicated to Harry Potter either despite what is being worked on for Harry Potter either. All Universal has for Harry Potter is 2 lands for the 2 theme parks.
