He's going to announce on his birthday, which is in the middle of April. I think Kansas has a leg up on all other schools. From what I've been told Pitino hasn't contacted Matthew since November.
Those who know don't talk. And those who talk (usually) don't know. My guess is that the Hurts are not blabbing all over Rochester what their plans are, which is a wise move.
That having been said, it would seem almost impossible that he would not have some contact with the family with a brother on the team.
