The Hobbit sets revealed at last
It's a bit lo-res but you can just about make out what they'll be like.
Hopefully someone will do a decent scan of it soon. If you know more about it, or if there is one out there already, please post in the comments.
Update: Missingno has provided some great scans on flickr. I've added them here (I hope he doesn't mind :-) ) but check out his gallery for higher-resolution versions.
