Not sure if this has been posted before but...
So far the point of view for books 1-4 have followed a radiant (or soon to be) of a different order.
which would follow the pattern. I think the the next 4 will also (not sure what sequence). With the books being from Jasnah (elsecaller), Adolin (hoping edgedancer), Renarin (truthwatcher). For dustbringer i have no idea (maybe moash if he, loses the honor blade and gets a redemption arc). But for Stoneward i think we could have Taln for POV and get to the real meat of his and the rest of the heralds backstories.
