Middle Earth: the theme park?

According to Cinematical, there are rumors that Universal Studios is toying with the idea of making a Lord of the Rings theme park (presumably thanks to the success of its Wizarding World of Harry Potter attraction). I'm assuming this will be tied in to the release of the long-awaited adaptation of The Hobbit, which I understand will be split into two parts, directed by Peter Jackson, and released in 2012 and 2013.
