Saw a Reddit thread talking about flashback characters for the next books. Spoilers included for those that are waiting, but it's from one of Brandon's WOB.

We know the flashback characters. I may get the order slightly wrong for the back half, but I believe it will go Szeth, Renarin, Lift, Shalash, Taln, Jasnah.
So sounds like we will finally figure out what made Szeth realize the voidbringers were back in the next book.
