A bout with Undertaker, and I refuse to accept anything else. After being a top name for over a year and a half, he should at least get a big match with Undertaker since he doesn't get to headline the event in the world title match. Feels like I've mentioned this a million times before, but the obvious set up is Punk wanting to end the streak because he wants to create the biggest Wrestlemania moment ever, something that will by far top anything having to do with Rock or Cena or anyone else doing anything else. (It might be Taker who comes out and offers Punk the chance to do it by stating that it's the #1 way to gain respect from everyone.) If Cena/Undertaker wasn't an obvious shoe in for WM30, and if I didn't think Punk was taking time off after Wrestlemania (or maybe Extreme RUles), I might actually speculate the odds of WWE/Undertaker offering the streak to Punk.
