I think he will. Ukraine is suffering a major political upheaval right now, his attention will (rightly) be focused on that for the immediate future.
Good point. Personally, I like the K brothers, particularly Vitali, but if they were both gone we'd get to see way more top level contender fights than right now. Something needs to be done to so we can have decent contender fights that give people a better sense of how good contenders are as long as the K's are around. The organizations should 1. have more rational rankings (people like Ortiz have no business being ranked in the top 10) and 2. have more frequent eliminators.
He should be stripped of the belt. He has kept the title without a defence for over 15 months.. disgusting and a disgrace.
