I really hope the IFBB goes in a completely different direction once Ronnie retires.
They rarely choose the best person competing, but, rather "select" someone to be the new mr. olympia.
I wouldn't be surprised if Dexter/Melvin wins the next one (if they go in the smaller, more aesthetic vein) otherwise, I bet Branch/Cutler/Gunter will win it (if the go for the freaky/huge).
At this point though, any change would be good.
