I think UVa's loss could hurt them, but not Duke's. Then again who knows. UK is a lock, that's about the only sure bet. I personally think Villanova is to if they win tomorrow. I suspect Duke is as well. The 4th spot could be up for grabs though and I'd say Wisconsin and Arizona are the answer's to your question. Again, just MHO, but I think Arizona is the better team, but Wisconsin probably has the inside track. This is a UK board so a little horse racing analogy seems appropriate because it looks like a close race down the home stretch.
