Yeah, out of those three, SummerSlam is the most in danger. It's pretty much the only PPV left without a gimmick.
Though with them trying to make it similar to Mania with Axxess and all the city pushes, I think it's pretty safe to be honest.
Let's just hope he doesn't get it in his head that battle royals are "outplayed".
I COULD see him changing the Rumble's name, though. What's so royal about it anymore anyway? You can't even say King announcing because he's barely a king anymore.
