I believe Paradox (PDI /Paradox Interactive) will only be the publisher, of any future games, or at least it won't go to the core devs (PDS/Paradox Development Studios). PDS is only involved in the likes of CK, EU, HOI, Victoria, Sengoku. Their first venture outside the comfort zone was canceled (Runemaster).
Pillars was only published by PDI and developed by Obsidian. Other notable games published by PDI: Cities Skylines, Majesty, Tyranny, Magicka.
Let's just pray that we will be saved from bugs (something else Paradox is notorious for).
