Early WrestleMania 27 & Royal Rumble Main Event Plans Revealed
Based on WWE's reported plans, it would suggest Barrett wins the WWE Championship at Survivor Series and subsequently loses the belt to Cena at the Royal Rumble, likely setting up Cena vs. Orton for the strap at WrestleMania XXVII.
Undertaker, however, is in desperate need of shoulder surgery, and there is much concern internally that if he gets it, he won't be healthy in time for WrestleMania XXVII.
Of course, none of this is confirmed and plans can and likely will change numerous times in the coming months. It's almost impossible to predict any WrestleMania matches at this point due to WWE's creative plans constantly changing on a week-to-week basis.
