Well champion always has a rematch clause.....
That was my feeling as well
My guess is he screwed up his promo. It makes sense all around that it would be a triple threat though. Cena said he can't beat them, and has to face them both making him an even bigger "underdog". Plus Rock/Cena needs something else in it to sell a rematch to the fans. The title isn't enough. Punk could be though.
Punk forgetting about the title and calling out Taker for Mania, or Taker showing up and having a problem with Punk doesn't really make sense if you stop and think about it. Punk is obsessed with the title and being in the main event. He would do whatever to get in that match. Taker makes more sense for Brock with his tie in with HHH and having HHH calling him back.
Shield or Lesnar must have to interfere with the match making it a triple threat.
