Notre Dame, they have been recruiting him for some time and the schools he seemed to be most interested in besides Iowa were all East Coast. Katenda could potentially start there as a freshman as well, with some graduation losses at Notre Dame.
It wouldn't surprise me if he went to Wake either based on the same story, start early and play a ton. The difference between the two is Notre Dame is in better overall shape as a program right now.
Still, in the end, I would not simply count Iowa out as Fran has been recruiting him for some time.
