No. Those are known NPCs from the game's backstory.
The jedi is the guy that gets killed by Malgus during the Sacking of Coruscant-trailer. Shae Vizla, the Bounty Hunter chick, is also present.
The trooper is in the Alderaan trailer, together with Satele.
Ah, I didn't know that.
Thanks for the clarification. Then I guess these two could be characters in the storyline for the expansion.
