Dan Rafeals colume on ESPN.COM says that this is pretty much a done deal.
The only problem is that Wlad wants to fight in June and Lamon wants to fight in AUgust. Rafeal lays out why this fight is going to happen- Pretty much there is no one else to fight, for Wlads Summer HBO date, and none of the Other alphabet belt holders will be avalible to fight until Wlads November HBO date

Valuev- He has a fight in april and as everyone behind the scenes knows, if he gets past Ruslan he will fight soft opposition until he breaks Marcianos record

Briggs- has a june fight with sultan

And the WBC title is tied up for the rest of the year.
