Let's pick 'em. I'll start:
Georges St-Pierre Vs. BJ Penn - Despite the fact that BJ pretty much beat the crap out of GSP in stand up, I'm thinking that GSP will take it again. GSP should be smart enough to not do another kickboxing match with Penn, and his wrestling is good enough to make that happen.
Lyoto Machida Vs. Thiago Silva - Probably Machida. And while I like Machida's character and skills, he is the MOST boring fighter I think I have ever seen. Remember the fight with Tito?
Stephan Bonnar Vs. Jon Jones - Pulling for Bonnar.
Karo Parisyan Vs. Dong Hyun Kim - Don't know about Kim, but Karo has been very uneven in his MMA career. If Karo's on, he should take it.
Nate Diaz Vs. Clay Guida - Looking forward to this one! I think Diaz will take it, but Clay is a hell of a fighter, too. Should be a very exciting match.
Jon Fitch Vs. Akihiro Gono - I like Fitch here. Too bad what Dana is doing to him now.
Chris Wilson Vs. John Howard - dunno
Jake O'Brien Vs. Christian Wellisch - not sure
Matt Arroyo Vs. Dan Cramer - dunno
