They've said already that it won't be Barnett, but that people wouldn't complain about his opponent. I've seen rumors of Vitor, but nothing too serious. I think dream would probably let affliction borrow Cro Cop, unless he's busy at the time (pretty sure he is). To me, the candidate that seems most likely is kimbo slice. Affliction is holding this event on free tv, and Kimbo still has drawing power. Of course he'll be expected to lose badly, but that would kinda be the point. For those that haven't seen Fedor yet, what's a better introduction than the complete domination of a known name? Of course this is just a wild guess on my part, and I'm not even sure the contracts would allow it, but monetarily it makes a lot of sense to me for Affliction.
