About the scheduling. He plans to start writing the next Stormlight Archive book right after he turns in A Memory of Light. He hopes to write two books for the Stormlight Archive in a row. The first of those might (very early estimates) be released at the end of 2012, or early 2013.

He talked about the link between his magic systems. One of the core principles is 'investing'. In a lot of his systems people are through some mechanism invested with magic powers. In Elantris through the Shaod, In Mistborn it's genetic, in The Way of Kings it depends on what someone has done.

Objects with almost sentient behavior like Nightblood in Warbreaker share important links with the spren from The Way of Kings. If you understand the spren you will understand a lot about the connection between the books.

The Mistborn series was sold as three trilogies. The first trilogy (the one we know) is set in medieval/16th century technology and is fantasy. The second trilogy will be set in the current day, or at least with the same kind of technology. This makes it urban fantasy. The last trilogy will be science fiction set somewhere in the future. Of course, all of them have the Allomancy magic system to get things interesting. The short novel The Alloy of Lawthat will be released in the fall this year is set between the first two trilogies so the tech level is around 18th/19th century with steam power. Brandon said it was about some Wild West-like character getting involved in a murder investigation in a city. So Clint Eastwood meets Sherlock Holmes in London.

Brandon answered that we would have to wait and read it later. When asked in what book the answer would be, Brandon was vague. It would probably not even be revealed in Stormlight Archive book 10.
