Over at the 17th Shard, a new interview has been posted that has some pretty awesome points in it. Here is a link to the post on 17th Shard:
Brandon Sanderson Interview Thread

The most interesting part to me was his talking about the Interludes, which was basically just a way of world-building by the use of occasional short stories.

He also goes into detail about The Way of Kings Primed, his original ideas for the Stormlight Archives, as well as talking about his thoughts on who the main characters are/were, and how much “screen time” they will get in the next few books. Best part? We will get a “flashbook book” about Szeth!

It’s a 40-minute interview, and there are tons of awesome things in the interview that I didn’t talk about here, definitely check it out!
