The trailer for HK-51 states that the droid is “under Belsavis.” In the beta, there were significant references to HK-51′s ship being on Hoth. In fact, the ship is still in the game available for anyone to find.
I wonder if the quest for HK will take you to Hoth, or if the entire quest line will keep you on Belsavis?
