I seriously believe P4P it will be Donaire but he will not be known enough to the mainstream. The recognized face of boxing (RJJ, DLH, FMJr) I believe will be Khan if he doesn't get KO'd anytime soon. It's right there for him to take. Ward doesn't have a star personality that counts and I see him getting knocked off when he moves up because he's a big 168er and stated he will move up even to heavyweight if he can.
Khan. Rios. Ortiz. Canelo. Gamboa. Lopez. Honestly, these are just suggestions, I don't see any future megastars at the moment but I'm sure one or two will emerge.
Khan will be around. He will be around. They all plan to leave early. The only ones who leave at an early age and never come back are those who are either traumatized or ruined.
Canelo has it all bar being fluent in English, anyone know if he's working on that like most other fighters do?
