Here's Gandalf, Dwalin, Bombur, Bofur, Bilbo, and Balin, in minifig form. Some of the online forums have guessed that this may be the mythical Bag End set.
A few of the Hobbit minifigs have been teased above. Apparently there will be more to find out a SDCC (San Diego Comic Con). Wow this looks awesome! And on top of all of that, we finally get some white hair! Hooray!
