Personally I do not think that this fight will happen.
Dana also said that if Anderson beats Maia, then GSP vs Anderson would happen. Anderson did beat Maia, but because of his distrespectful performance Dana said that GSP vs Aderson is not happening.
Condit is a legit threat to GSP, and GSP is coming from a very long layoff. I do not know if GSP is going to win the fight, and if he does, I doubt that it will be by some impressive way.
And secondly, the weigh stuff also is going to be an issue. GSP will not feel good fighting at 180, and I do not think Anderson is going to want the fight at 170. He would have to cut about 40 or 50 pounds, that is a lot.
