CroCop's got 3 scheduled fights in Japan with a possibility of extension at any time. If he wins his 3 fights under his DREAM contract I see him moving on to Fedor. Win or lose, he'll come back to the UFC after that. He'll most likely get cans for his three fights, but if he loses any of those, I'd say his chances of coming back to the UFC.
If he can win his three fights, I think we'll see Mirko back in the Octagon by late 2009 and hopefully he'll knock a few heads off and redeem himself for his initial performances in the UFC.
