I'm all caught up. Rereading for clues now.
Spoilers for my speculation
I think the first arc will be primarily the end of focusing on Roshar. The second one starts focusing on the Cosmere as a whole, with much more worldhopping. Haven't decided if they make Odiom the big bad for the entire series or if another force comes in. After reading the last Wax and Wayne Nobel, I wonder if it's Odiom that is behind the Red Mist that is surrounding the planet.
