While I love Studio Ghibli films, I don't see any of them making an appearance at a U.S. theme park, be it Universal or Disney. Ghibli films, while excellent and some of my favorites, along with most anime in general are a niche market that many in the mainstream have little knowledge of. That coupled with Ghibli's uncertain future (they haulted all production last fall to re-evaluate the company after Miyazaki's retirement from directing and there there have been reports that the studio may close their doors for good.)
