(Reuters) - Even in Las Vegas where fortunes are won and lost on the roll of the dice, Floyd Mayweather Jr. and Manny Pacquiao have Sin City abuzz over a megafight that will generate millions and reshape the sport business landscape.

From $100,000 (£65,664) ringside seats to $150 million paydays, Saturday's long-awaited showdown between the greatest fighters of a generation is expected to be the richest fight of all-time and smash records in knockout fashion.
