Probably still Wlad, I see him fighting maybe 2 or 3 times, which will be Povetkin, some lame oppenent (Thompson, Austin) type caliber, and then maybe Haye to end out next year. Peter will face Vitali, then the winner of Virchis/Gomez. I see Wlad staying at the top, while both fighters will win there matches, Wlad will still be considered the "Real" champ if you will.
i reckon wlad will spark out povetkin, valuev then chagaev so he'll hold 3 belts. vitali will destroy peter then end haye's life or chase him back to cw. so wlad will be #1 and vit #2. the division will be cleaned out
