Mayweather/Pacquiao fight does anyone agree?

Granted Mayweather may not want to risk his undefeated record, but with all these allegations(drug testing excuses) and coward-calling (saying Mayweather is ducking him) wouldnt this fight be the highest grossing fight to-date? This fight is going to happen I believe a good amount of it all is publicity. Even boxing fans and new boxing followers are begging for this fight to happen. In the end couldnt all this publicity prove money walks bullshit talks? This fight will happen because of the profit and demand anyone else smart enough to come to the same conclusion?
