It doesn't depend on him but also on name opponents that want to do business with Don King ( exception taken for DK fighters of course, like IBF SWW champ Cory Spinks or Ricardo Mayorga). The obvious and logical showdown ( farewell fight) would be between Tito and Hoya either at 154 or at 160 but it is not likely to come off, so it would better that DK, Felix Sr and Tito start looking for Sturm, Castillejo, Forrest, Mosley, Ouma, Santos or Simms... Can't be a young, active title holder like Dzinziruk or Alcine, and it can't be a strong, seasoned and able 160 pounder either or else, Tito may well retire right now.
he should go back to middleweight. he really should be at 154, but i doubt if he'd want to drop that far, even though that's where the big fights are at.
