There is said to be a lot of panic within WWE right now due to creative plans.
When the decision was made to switch Daniel Bryan and Big Show in the hunt for the WWE Title, the idea was that Show would have a big Survivor Series match with Randy Orton and then follow it up with an even bigger match at TLC with Triple H. A few days before Survivor Series, they dropped the idea of Show vs. Triple H and the plans for TLC were Orton vs. Show in a Tables Match, which is why Show chokeslammed Orton through the table on RAW.
One idea for Cena was to have Big E Langston turn heel and have them feud over the World Heavyweight Title. Obviously when Survivor Series was over, both of those matches were off the books and the new TLC main event was Cena vs. Orton with both titles hanging in the air.
