Uh.... SGR's on Makeb is ONLY the beginning, and SGR's with Companions are STILL in the works and will be coming.
i am doubtful about that.
There was already an interview in which it was related that expansions on companion conversation are very low on the priorty list.
The "still in the works" answer does nothing for us. We have been hearing that kind of answer since chat bubbles are comming soon
