I actually want this to happen because it would be awesome to lead up to. You got Rock/Cena which still hasn't been settled and Cena/Punk which in my mind also hasn't been settled. Then now we have Rock/Punk, which I would just be disappointed if there wasn't more than one match to this. I think having that triple threat would cover all three group fan bases. It would be the equivalent to the Survivor Series match with Rock/Austin/HHH. It would be terribly generic for WWE to just let Cena beat Rock at mania, it's just so bland. Having a triple threat would add so excitement to this match IMO. I don't want to see Punk vs Taker either because that's just going to be predictable and probably won't be a good match because Punk isn't much of a storyteller wrestler, he's just a technician.
