With all due respect to the enthusiasm on display, I have to say that I am actually pretty unhappy about the news. Splitting it into two movies, and injecting the Dol Guldur and White Council sequences, will destroy the flow of the narrative, and ruin the charm of the real story. I'm actually pretty bummed right now.
Dol Guldur and the White Council are important to the history of Middle-earth, but they have nothing to do with the story of The Hobbit. If they had been important to that story, wouldn't you suppose Tolkien would have added them when he revised the story to remove the conflicting elements from it?
