Jeez, throwing 'Mags in the King of the Ring is very surprising. For some reason I don't think he'll win, but it would be stupid to count him out completely. It definitely adds some intrigue to the tourney since he would be the biggest star in there thus far.
For some reason the only person I can think of for new commissioner is Mick Foley. While he was a heel last we saw, I guess he got what he wanted at 'Mania and he could come back as a face. I can't think of anyone else right now, so Foley's my bet.

@ Christian attacking Undertaker with a soup bowl. Sounds like an epic angle.
