It's easier to call for Klitcschko vs Mickey Mouse than for Klitschko vs Klitschko. They promised their mother that they would never fight each other. It's not going to happen. Klitschko vs Peter would be good. Klitschko vs Valuev would be a huge hit for the freak factor alone.
Neither of these guys are top 30. They had their day (about seven years too late, even then) At $5.95, it wouldn't garner 100,000 ppvs The biggest ppv event that's remotely possible would be a June 2008 bout between Vitali and Lennox.
If somehow you could engineer a situation where Vlad steals Vitalis boyfriend and they fight each other, thatd create a great PPV opportunity.
