I really doubt it.
But going by the same logic they could add:
The Thexian Elite
the Draxian Hegemony
The Worldweave of the Noisesome Reek
the Ulumeathic Leage
the Church of Dracolith
- all are races mentioned in the current rulebook, and theres probably more if you go through it.
There just there as filler and background stuff, i cant think that any will ever really make it into the game.
It like with the BL novels, writers can pretty much just make up stuff to make the universe a little cooler.
Only the Fearful fear Fear.
