ESPN has a bracketcaster which runs simulations of the tourney. I ran one and this is what I got.
Midwest--UNLV vs Tenn in the 8, with UNLV going to F4

East--WV vs. Kentucky, with Kentucky in the F4 Makes sense
South--Purdue (cal had taken out Duke earlier) vs. Nova in the E8, Purdue in the F4.

West--N Texas upsets KSU

, Xavier vs. Cuse in the 8, X to the F4.

So this thing has a 1, 4, 6, and 8 team in the F4.
UNLV beat Xavier
Purdue beat Kentucky
UNLV as an 8 seed wins Championship. WTG Lon Kruger!
ESPN can be so fracking Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!).
