Just announced major UFC on FOX change

Mark Munoz is out and the co-main event for UFC on Fox January 28th is now Chael Sonnen vs. Michael Bisping with the winner getting a title match against Middleweight Champion Anderson Silva.

In other words, the match most people thought should have been made in the first place.

Who would you have the most interest in for Fabricio Werdum's next title defense?
