I think Wax and his dealings in Elendel would make for a great serial, in the form of the Harry Dresden Files, and other such works. If not that, I would love to see Sanderson return for a couple other short novels, or a series of short stories and novellas. I think the setting and the characters are rich enough to support several stories.

I was struck again by just how cinematic Sanderson manages to be when he writes his climatic action sequences. The images seem to be cast directly into your mind, like you're watching it on a big screen. There were some pretty thrilling moments in this story.
