There’s been discussion of a Part 2 for a while now,. Does anyone know anything more?
The second and third BoB campaigns were not supposed to come out before the Throne of the Void rpg was completed. There has been no announcement about TotV for a long time.
Moreover, the authors are also working on another rpg, which is at the playtest phase: Project Perseus (https://www.geeknative.com/129412/evil-hat-announce-two-new-rpgs-apocalypse-keys-and-project-perseus/).
So I guess all of us BoB fans will have to wait a little longer!
