Haye's back-up plan=WBA Regular Title
As of October 2012, Haye is the #1 challenger in the WBA rankings.
Povetkin must fight Klitschko soon or be stripped. So Povetkin-Klitschko will happen next Spring or Povetkin will be under pressure to vacate.
So if Haye doesn't get the fight with Vitali, then he fights for the WBA regular title. Perhaps vrs. Ortiz or Chagaev.
This would give Haye room to build up (defend his fake title a few times) for a Wlad rematch when he's ready.
