This is everywhere, so I'd be surprised if you haven't heard, but
Peter Jackson will produce a new Hobbit movie afterall, along with a sequel! I guess he resolved his differences with New Line. Don't get too excited, though, we have a long wait:
The two “Hobbit” films – “The Hobbit” and its sequel – are scheduled to be shot simultaneously, with pre-production beginning as soon as possible. Principal photography is tentatively set for a 2009 start, with the intention of “The Hobbit” release slated for 2010 and its sequel the following year, in 2011.
