Interesting that the story isn't that New Line might still buy the rights, but rather that MGM wants Jackson for an MGM production.
But from the way Sloan is talking it sounds like they've probably come to some sort of deal. A project like this is just too good to be left on the shelf, it's an instant blockbuster with a huge built in audience, hence why they are wanting to make two movies and not just one, sort of the antithesis of the problem with LOTR and Harvey Weinstein!
