Please try reading my post more carefully.

This Story Mode Roster only has TWENTY (20) slots, and if Geralt, the guest character, is getting a story mode inclusion that means that there's only 20 characters that aren't bosses, Edgemasters, and whatnot. That also means that total roster will include 20 characters and two or three boss characters (or two boss characters and one DLC guest through pre-order or whatever).
We have 15 characters revealed thus far, we have 20 slots in Story Mode. That means there's only FIVE (5) more reveals left. The remaining character slots are going to be slotted for boss characters for the base roster. Cervantes and Astaroth are two more reveals we know are coming. The remaining three slots on the story mode are likely to be SC1 returners, Hwang, Seong Mina and Rock.
This is the very last time I explain this. Keep hyping yourself up for disappointment.
