I'm starting to think that it's going to be Bishoff and not JR. All they would have to do is have Vince come out, call Bishoff out, and say that he's fired because he is the GM and he couldn't keep control of his own show, which is the reason Austin was able to get to all of the McMahons. Vince could say that he has more important things to deal with other than RAW, which is why he brougt GMs to each show in the first place, and he needs guys who can keep control of the guys like Austin, Cena, etc...
That makes perfect sense to me.
If they change plans at the last minute because Goldberg pulled out, I bet that's what they do.
