Who is the next opponent for Juan Manuel Marquez? Katsidis, Hatton or Someone Else?

36-year-old Mexican great Juan Manuel Marquez is pencilled in to fight again probably on May 1st, in Las Vegas (according to BoxRec), but there is much uncertainty about who the lightweight/light-welterweight will face. We have all read about how former 140-pound king Ricky Hatton,rumoured to be back in training for a 2010 ring return, has been in talks to face "Dinamita." but nothing has been officially announced. While warrior Michael Katsidis, the interim WBO lightweight champion (Marquez holds the "real" WBO belt) is hoping it will be he who faces the Mexican legend next, in a fight that will decide who is the main man at 135 pounds.
