I gotta think that Pacquiao-Mayweather is the next big "superfight" that is actually plausible. really, what else is there in the Boxing world? Boxing REALLY needs some interesting heavyweights.
just from piecing together what i've read, i think there is a big disparity between the weights. hatton moved up from 140 to 147 to fight Mayweather (maybe mayweather moved down too?). Pacquiao moved up to fight Hatton at 140. Can Pacquiao moved up to 147? Mayweather below 147? Pac fought DeLaHoya at 147, but DeLaHoya was old and crap
