Except, he is. He's the biggest draw the WWE has had since Austin/Rock, whether you like it or not.
I expect RVD will lose by some kind of cheating, possibly Cena "accidently" hitting him when trying to get Edge, then Sabu/Angle/Show says on ECW TV that RVD didn't represent ECW at the PPV, and they attack him to start ECW's first world title feud.
