3. John Cena
You can never count the 15 time WWE World Heavyweight Champion John Cena out of the picture.
With most of the Top WWE Stars not available due to various reasons, Vince has contacted Cena to return before his scheduled return date (which was in December before the TLC PPV).
While Cena will most likely not become a 16 time WWE World Heavyweight Champion at Survivor Series 2015, you never know what Vince has in mind!
