Nighsister spirit

I'm going to take a wild and random stab and say that its one part Halloween, and one part possible Separatist faction pass. Just like last month the login toon was ROLO, but the focus was bounty hunters leading up to the reveal of legendary Chewie and needing bounty hunters to unlock him. Perhaps Separatists will get a pass/rework and some new toons will be added to the game. There is the fact that the IG-2000 works with "other droid allies" and that Grievous did go to war with the Nightsisters. Maybe we'll get new droids, a Grievous rework, and a new capital ship for them? I'd love to see Grievous with The Malevolence or Nute with a droid capital ship.
