I think change is most likely to come from Saudi Arabia, with their proposal to get rid of belts and the “win the belt,keep the belt” structure of the sport, shifting instead to a unified boxing league. They’ve already shown they have the money to consistently make the big fights happen and get the stalling out of the way. https://amp.marca.com/en/boxing/2025/01/12/67841dc7e2704eb4a78b4590.html
The great thing about boxing back in the days of the WBC/WBA era's was the fact most champs actually wanted to unify. Even the stars that could've made money without unification.
