Seeing that The Rock already agreed to appear at Extreme Rules, what are the probability of his win at WrestleMania? To me, I can actually see him win against John Cena. That would be good, and will only build up this "Cena can't beat The Rock" even more. And at Extreme Rules it might be a good way to turn Cena heel. He might get very frustrated that he didn't win again, and slowly turn himself 'heel' until his clash with The Rock at Extreme Rules. What do you guys think?
