I'm in no hurry to find out. Canelo is the most obvious pick. Donaire is no kid but he should be very active in 2012 and start to gain notice with the public. If Russell Jr continues to develop he can gain a following over a period of years.
Like you said, no hurry to find one! How about Gamboa..I mean isn't he one of the most marketable fighter in terms of excitement? But I guess that since he is "only" Cuban...
Uzzy Ahmed. By the time he moves up to super flyweight, he'll have already become the top earner of his generation. His unification with Daiki Kameda for the WBA/WBO/IBF/WBC/IBU/WBF/IBO/WBU/IBC/Quaker State/Ring Mag titles will shatter the previous single PPV buy record and restore the global economy to pre-recession highs.
I love watching Gamboa right now. He is probably my favorite to watch and its great that we don't have to pay anything to see him fight right now. But speed is one of the first things that leaves you with age so I don't know how long he can last with his size disadvantage.
I think he will emerge out all the young talent we have from Bantam till lightweight. Mares, Moreno, Donaire, Gamboa, Juanma lopez, Ramos, Russel Jr., Broner, Rios, Guerrero. I think and def hope that we are going to see a lot of great fights between these guys in the coming years and a few fighters will come out as PPV stars. Mares and moreno probably will be too small. my picks are Donaire, Gamboa, Broner and Rios.
