The WBC is the only sanctioning body that is considering this fight a defense for Taylor's belt.
Neither guys are paying the WBO fees which means if Wright wins, the belt becomes vacated. If Taylor wins or a draw he will retain the WBO belt.
The WBA is looking at this differently. Taylor was willing to pay the negotiated fee, but since Wright refused to pay his share, the WBA is basically saying that regardless who wins the fight, Taylor will be dropped leaving Sturm as the sole champion.

By next week, if Taylor wins he will have the WBC and WBO belt only.
If Wright wins the WBC belt will be his, but the WBO will be vacated.
