1. Rysn will become a radiant (dustbringer I hope)
2. Lirin will be revealed as radiant in training (Three radiants from Kholin clan, why not another radiant from Kaladin's lot)
3. Shallan's eldest brother is not dead and possibly another radiant
4. The bastard son of victorious Jah Keved's Highprince will join the ranks of KR (There is something about him that I can't describe)
