Well, Citadel's official description proves that we're dealing with a "new villain".

[From the Xbox Live Description]

"Commander Shepard and the Normandy crew get a much deserved break, but their shore leave is short lived. Face down a new villain before catching up with old friends from Mass Effect 1 and 2."

Personally, I'm more interested in seeing how Kolyat's gonna play a part in this thing =3 (he's in the trailer for about half a second so yeah.)
