depends how these next two fights go, with a win on one-side of either of these fights their is an incredible amount of leverage and demand for the bulk of the spoils.
Pac's camp will probably offer Marquez $2.25M flat, take it or leave it, if Pacquiao continues winning by the time they negotiate for a third fight.
If Pac beats Cotto and Marquez beat Mayweahter, and then we get Pac vs JMM III, I think i will cream my pants That fight will be the biggest and best fight ever.
