I just got back from the Phoenix Comic on, where Brandon is a guest at, and I must say it was an honor to meet him. He read parts of Wax/Wayne 2, Legion 2, and the Taravangian interlude in WoR. There weren't a lot of cosmeric goodies, but I did get a couple interesting tidbits in relation to Mistborn: Ruin would have had to manifest to reabsorb the atium, the Well of Ascension did not come at a price to Preservation's power, and perhaps the most interesting one. Burned metals are turned into a different form, and will eventually return to the planet. The Pits of Hath sin are meant to foreshadow this.
There were a couple of cosplayers, with one particular group dressed as Sazed, Vin, Elend, and Tindwyl. I have audio of the spotlight (which includes the readings), but I don't know if I am allowed to post it. I probably will post a picture of the four costumers later.
