On the just-started pre-show for the 2015 Royal Rumble, Renee Young actively promoted the idea that The Rock is in Philadelphia
First they promoted the instagram post of The Rock in South Philly:

Then Renee talked about the response of Lana, manager of Rusev:
.@TheRock doesn't scare me or @RusevBUL! He is just another pathetic American too busy stuffing his face with cheesesteaks in Philadelphia!

This could indicate that The Rock and Rusev will continue a storyline started on WWE TV in 2014.
There are other rumors that The Rock could even be inserted into the Royal Rumble match.
