Couple of questions I heard asked that we'll probably like: Q: When will Hoid's books come out? A: Well, there's the Dragonsteel series which is [kind of] the prequel, and then he's a main character in the final Mistborn trilogy.
Q: What are Hoid's plans for his Lerasium bead?
A: {Smiled and pulled out a RAFO}
There are a couple more that I can't remember exactly that I'll edit in once I talk to my buddy who asked.
