I think by the end of 07 Klit will be the IBF and WBC HWC and Valuev will be then WBA and WBO HWC with a total unification sometime in 08, to many belts, to many mandatories for someone to totally unify in 07 IMO + like someone said, to many new champions who wanna make a few bucks with a few easy defenses rather than growing a pair and trying to unify
