#1: The Deadman rises

Undertaker lost at Wrestlemania back in April in what was widely speculated to be his last hurrah. Although no official statement has been released by the veteran superstar or the company, few expect him to turn up again at the ripe old age of 52.
However, Undertaker still has some unfinished business with John Cena and there have been rumours of him returning to interfere in Cena vs. Roman to have one final feud with John Cena.

When that gong goes off again, expect the whole arena to erupt and the whole internet to break down. Undertaker returning could be a huge swerve and a Cena vs. Undertaker dream match could finally see the light of the day.
