The rivalry between CM Punk and John Cena is expected to get official closure sometime prior to Royal Rumble according to F4Wonline.com
The idea is to finish what didn't get to conclude due to Cena's injury in the month of October. Initially, WWE officials had discussed having a triple threat match at Survivor Series featuring CM Punk vs John Cena vs Ryback. Obviously they decided to go in the direction of the traditional Survivor Series match instead.
WWE officials would like to wrap it up before WrestleMania season begins.
