According to yahoo sports, at least, the NCAA itself revealed the 10 who drew the assignments; the article implies it was done to increase transparency in light of the public discussion of officiating in the last few weeks.

The weirdest part of the article is this:
"Game assignments for the first semifinal will be announced an hour before tip-off of that game. Assignments for the second semifinal will be announced at halftime of the first game, and the officials for the national championship game will be announced an hour before that contest. No official works more than one game during the weekend."
Once the crew gets announced for the second semi-final at halftime of the first, you'd have to be pretty stupid not to be able to figure out who the crew for the final will be. Isn't it a pretty signficant departure for the NCAA to have the names of the championship officials out there in the public for 48 hours? I know that traditionally, they are not even supposed to be on site until after the semis. Though it's not always a particularly closely guarded secret, I thought they were worried about public perception that coaches would coach to a particular official or crazy conspiracy theories about vegas dudes with paper bags of money.
