Perhaps it will be an "exotic" faction like Zerrekania or Ofir. The only other faction I can think of from Witcher 3 is Novigrad, which was independent.
They did say the new faction would be "different". Who knows. Hopefully they don't just add it to add new things to the game, but have a real purpose and intent behind it.
