Heard today its very, very likely BYU or Utah. I had been told Stanford for several months but it sounds like he has chosen to play close to home. Could still pick Stanford but it sounds unlikely. I have not been told this part, but I think he is going to commit to the Utes with the hope the program is not a train wreck when he returns from his mission (he is a mission first kid). If it is, he has the option of transferring while on his mission.
BYU did its job on his OV and the staff has done a fantastic job recruiting him. If it is Utah, its because he and his extended family are very big Ute fans. Of course, playing in the PAC-12 has a draw as well. We shall see soon enough. I'm hopeful, but if I were betting I would say its the Utes based on the vibe I am getting from my source (he's a ute so who knows).
