Honestly guys, I very logically don't see Taker vs Punk being for the WWE Title. Hear me out.
Factor 1: Punk will not end the streak. So, in this scenario, Taker - a man who fights once a year - would walk out of Wrestlemania the WWE Champ. It's a most fitting and touching sendoff, but one can only imagine Taker will end his epic career at Mania 30. If I'm wrong, would they have Taker vacate the title after 29? I don't know.
Factor 2: Rock vs Cena at 28 was 'Once in a Lifetime'. The only way to make it 'different' than last year, would be to make it for the biggest prize in the company. I would be shocked if Punk doesn't lose to the Rock at the Rumble. This is Vince McMahon's company. Ole Dwaynie and Ole Johnnie will end their epic Mania rivarly 1-1, John will walk out of Mania with his Spinner Belt, and all will be 'right' on planet Earth.
Factor 3: They've already set us up for Punk vs Taker without the title, it's all about respect. Challenging Taker at Mania is the ultimate battle for respect and CM Punk will surely need it after dropping the title to The Rock. It also allows Punk to remain in an insanely high profile Mania match-up, despite not fighting for the title.
For a few months I was on the Taker vs Brock bandwagon, but I just don't see it happening. HHH is likely getting his Lesnar rematch.
