It seems quite possible to me for them to do a third movie, with so much to choose from in the Appendices. A third movie that serves as a bridge to LotR would be awesome -- and I think it could be done fairly easily with the material available, tying it in to both the Hobbit and LotR. I'd love to see more of the history of Rohan and Gondor, including Thorongil's travels and more of the battle of Osgiliath and Faramir and Boromir's dream that began their quest.
