Zuffa Versus World:
Heavyweight Unification bout: Brock versus Alistair Overeem
Lightheavyweight bout: Shogun versus Gegard Mousasi
Middleweight bout: Anderson Silva versus Hector Lombard
Welterweight unification bout: GSP versus Nick Diaz
Lightweight bout: Frankie Egdar versus Gilbert Melendez

These are all matches worth television appearences and could easily be broadcast on a PPV card. I think this would be the ultimate chance for UFC to demonstrate that they are the best organization in the world!
