I zoomed in on the picture from the Trailer and all three of their eyes are Black, though they are so far away you prolly couldn't color them and make them look like natural eyes.
So as of right now they don't match Cilan, Chili, or Cress's eyes.
Also side note...to anyone that has played or Watched Dot Hack GU. Do the Shadow Traid look like Adept Rogues to you? Namely Haseo?
