Well #1 Wlad said "I want a unification match"

www.klitschko.com "Vitali, what’s next? How likely is it that Wladimir will have a unification fight?
The likelihood of Wladimir carrying out such a fight is very high…But while the contract for such fight is not signed, it’s hard to speak with full certainty.

From all of today’s champions which one is most likely to face Wladimir next?
If there will be no force-majeure circumstances than it’s Oleg Maskaev. "

#2 The Maskaev fight almost came to fruition instead of the Brock fight

#3 Shannon Briggs called out Wlad at the press conference

#4 i have read about a Briggs-Valuev matchup from Maxboxing

I'm not 100% sure that any of these fights will happen but it's looking more likely.
