I think it'll definitely plays a part, which I why I'm puzzled he's not taking a tune-up first. It seems like all the eggs in one basket, a "for God's sake get me in the ring before I fall to bits!" kind of one-off deal just to achieve the Klitschko Dream (tm). It's what happens afterwards if Vitali wins the WBC belt again that concerns me. Vitali will retire again, the belt is vacant, end result is that Peter will fight for it again and could win it and then we're back to square one. Except Wlad will have had to wait even longer to have a chance to be undisputed and now a rematch win over Peter would mean even less than before.
