When will we see a book that basically revolves around the concept of the Cosmere and the shard-travelers? Basically, a book revolving around people like Hoid who can jump from shard to shard.
Third Mistborn Trilogy involves a lot of this. I MIGHT do some parallel stories showing more of what Hoid has been up to. He is a primary viewpoint protagonist of Dragonsteel, but that happens before all of the other books.
