At first I believed that Booker T would win since it's in his home-town (plus Joe's on going problems with Kevin Nash making look even more like a win for Booker.) but now I'm thinking Joe will retain because like Enigma22 said, why would he drop the title after becoming the first TNA Champion to walk in KOTM as Champion and walk out still holding the belt??
It's a tough one to call, but I'm going with Joe. 10,000 on him.
