That's what i'm figuring which is why I said one guy is the odd one out so to speak.
I figure we get Cena/Rock again and Brock/Taker which leaves Punk as the odd one out and even if he doesn't have the title facing Ryback won't be a big enough match given the title reign that he's had.
If they can get Austin to work a match then a Punk vs Stone Cold co-main event would be the shit.
You know how they forget about the brands around Mania time so Punk could easily find himself in the other title match against Sheamus too, or Ziggler if he's champ by then.
