Peter Jackson signs on to produce The Hobbit.
This is both a good thing and a bad thing. The Lord of the Rings suffered because three three-hour movies wasn't enough time to tell the story. Especially when you start adding stuff... but I won't go there.
I fear that two movies will be too much time to tell The Hobbit. It's not that complicated of a story - There and Back Again - but a lot happens, too much for one movie, but not enough, I fear, for two, unless they plan to really drag out the Battle of Five Armies for, like, half the second movie. And frankly, that wouldn't surprise me a bit. I don't know that I would mind that. I think it would be cool to see dwarf armies in battle - it has the advantage of never having been done. And they could really add to the depth of the story by including some historical information that ties the Mines of Moria, the goblin war, and the seven rings of the dwarves into the story in a way that isn't presented in the original Hobbit.
If I were writing the screenplay, I would start it with Gandalf's chance encounter on the road to Bree. If you're reading this, Mr. Jackson, I am available. I have trained myself, body, mind and soul, for this task for the last twenty years. Call ME!
