The thing I'm most interested in is the establishment of theYeah. Each book has a main character, and we'll get flashback sequences for that character as with Kaladin in book 1. Two five-book arcs as well. I'm looking forward to Szeth's book which is going to be book 3 apparently (although Sanderson may change his mind like with book 2).
new knights radiant and how they'll be established.I think Sanderson is setting up his characters to each embody an order of the radiants.
