Most have assumed that The Rock will defeat CM Punk at the Royal Rumble to win the WWE Title. While that is the popular opinion at this time, there have been other scenarios pitched where Punk would retain the title in some controversial fashion.
Word is that The Rock has been promised the WWE Title; so one scenario is that Rock could lose to Punk at the Rumble and then compete in the Elimination Chamber and win the title there. The plan would then be for him to defend the title at WrestleMania against John Cena, who may be the one to win the Royal Rumble this year. There are also rumors that CM Punk vs. The Undertaker will take place at WrestleMania 29.
