My Rumble prediction:
Zack Ryder returns at the Rumble, having been off TV due to Kane injuring him until then. He ends up winning, eliminating Kane last (possibly not eliminating anybody else). But he doesn't get his WM title match, and somehow this is Cena's fault. Possibly Cena wins the title in the Chamber and Johnny Ace won't let Zack challenge for it because Cena's already in a match with Rock. This becomes part of Cena's heel turn that happens at Mania, because unlike at TLC, Cena isn't willing to give Zack an opportunity. Not sure why he doesn't just challenge for the WHC instead, maybe he does but it's like a 4-way with Bryan, Henry, and Show and everyone gangs up on him? Or maybe Rock somehow ends up with the WHC so he can't get his shot at all?
