I'd be surprised if they were gone in 2 years. Chances are Wlad will still be exposing/chin checking the other top heavyweights, and we may still have Vitali knocking people out in the first round!
Helenius seems to be missing from the list. Not that I'd neccessarily pick him. There are also guys like Eddie Chambers and Arreola. Both are pretty talented, though a bit fat as well.
:deal If you're gonna include Fury then he definitely should have included Price. Fury's not gonna make it past domestic level in my opinion. Price has the potential to be a contender.
Clearly the poll misses a few of the most significant heavies, with no less than 60% chosing "other" at the moment. :bart
I think Wlad will stick around for about 3 more years- that'll give him enough time to pick up the WBC belt once Vitali retires, defend against a few top contenders of the next generation who've distinguished themselves by that point (someone like Helenius, Boytsov, Perez, Pulev, Price, Fury, or maybe even a dark horse who emerges) , then call it a career. Whoever's left standing out of that will then scramble for each of the belts as they open up. Accordingly, we'll probably have to go at least another couple years from that point before any kind of unification occurs again. I figure Glazkov will likely pick up one of the alphabet titles once that happens, as well.
