Only problem is, again, Vanitas is more likely to have connections to Ven, plus he's too short to be Xehanort. His voice isn't even the same! But it's not Riku's seiyuu, either. See here.
That being said, it's far more implied that Terra is Xehanort. The "friend" scene is Final Mix, the implications in Days ("So sleep has taken you again..."), the search for the Chamber of Waking, the hand-on-the-shoulder scene with Roxas... The similar appearances, even. Plus Terra looks to be the right age and height. Plus darkness.
My bet is that Vanitas might still have a connection to Riku, but I have a suspicion he has something to do with Sora, if he -is- voiced by Miyu.
