If Floyd and Manny fight outside of the USA that would be insane, it would really shock me because that would be a huge move by Floyd and it would make the fight more interesting in terms of international appeal
Floyd is very smart business man in boxing, and making it international affair would gain even more money, foreigners love watching washed up Pacquiao fight, so imagine them doing a rematch they are going to gobble it up if they do a world tour in places like China, Japan, Germany, Australia, Africa.
In the states the rematch will only do like 2 million buy stops, but globally it could be massive even bigger than the first if they have international ppvs.
People in America dont forget how boring the first fight was so international promotion would be good for this rematch
