Mayweather vs Pacquiao PPV Numbers

Mayweather vs DLH did 2.4million PPV buys, which is the RECORD for PPV buys. Mayweather vs Canelo did 2.2million PPV buys and Tyson v Holyfield II did 1.99million. What do you guys think this fight will do? Consider the fact that the fight is priced at like $99. Before the fight was announced, I thought it would do about 2.8 but the promotion for this fight has been crazy for the past two weeks. Floyd v Canelo was a big fight and it was one of the few fights where I heard people talking about it on the street in different places (not in your typical gym) but this fight, people are talking about it EVERYWHERE. People are making plans on actually buying the PPV unlike normal where everyone used to stream it. I can imagine a good buyrate here in the UK since its only £20 too. I can see around 3mill in the U.S Market. What do you guys think?
