The Rock & John Cena: Real Feud or WrestleMania Build-Up?

Question
Does The Rock and John Still Hate each other in real life? or are they doing this to build up for their Wrestlemania 28 match next year? and who do you see winning the match?

Answer
They never really hated each other. It all started when Cena was asked about The Rock, and John was honest with the comments. The Rock FINALLY came back to WWE after years away, with not even so much as an appearance on WWE TV outside his family being in the Hall of Fame.

Naturally the rivalry people wanted to see was Cena/Rock.

I see John Cena winning the match personally.

The reason being, The Rock is simply coming in out of no where and expected to take on a 10 time World Champion and win. We're talkin a guy who is active the entire time, every time. It just makes little sense that Rock would win. It kills all credibility for Cena as the top guy.

It's like when Rock took on Hogan. Sure, Hogan was the bigger name but Rock got the win for obvious reasons
