The story as I've read it, you'd enter the Wizard's throne room, though there'd be a wall down the middle of it so each set of cars would have its own room. The scary Oz would greet you, and then somehow a curtain would be pulled aside to reveal the "real" wizard who turned out to be the Gangster/Bandit that hijacked you earlier and disappeared in the Annubis scene. Then a curtain would rise up on the side of the room and replicas of all of the major AA's from the attraction would be there to take a final bow with the Gangster/Bandit.
I can't recall if it was an Al Lutz or a Jim Hill article I read that in. (Probably Jim Hill)
