I don't bisping or Rockhold stand much of a chance, GSP won't fight Weidman, I think rory is the one who will move up after GSP beats Hendricks and says he isn't going up in weight
I have to disagree with you here. While Weidman KO'd Silva, which was awesome, I think currently that Bisping and Rockhold are the better strikers. Bu Weidman is only getting better so who knows. I think that Bispings style could cause Weidman some trouble. I think people are forgetting Okami in the talk of contenders too. Okami is a tough fight for anyone.
I think if Munoz has a couple more fights and continues to look impressive then he could give weidman a good fight, not sure he can beat him though.
As for Belfort I see him being man handled, he could catch him but thats about it.
