That'd be cool if Bischoff returned and joined the nWo
I remember Bischoff used to be a commentator in the WCW. Before Toni Shivoni(sp?) became the main annoucner he was there, and because Bischoff joined the nWo Tony took ihs place as a sort of senior announcer. In the WCW, he was nWo's political power, booking matches and getting memebers that best suited the needs of the faction. If he shows up in her former role it'd be a bit redundant since Ric Flair now has that position.
