I don't believe this has been brought up yet, but the latest edition of The Interactive Interview features the "Nature Boy" himself, Ric Flair. It was a pretty decent interview as Flair is as open as he can be and he seems to be a lot harsher on Bret Hart in this interview than in his book. It's worth checking out...
Flair was on the panel version of Off the Record last week, but he wasn't talking too much about wrestling. He kinda seemed a bit lost, especially when Lansberg asked him why people should buy his book.
He does have a one on one with Lansberg that is being shown tommmorow on OTR, so Tuesday at whenever its on. That's probably the one people are waiting for.
Tommy Dreamer and Lance Storm are the only other former ECWers who come to mind. We Benoit was there and Eddy, but like someone said earlier I just cant see them joining, yet. They will have to bring in people from other organizations.
