i'm guessing that Cena beats Rock and moves into another program with Punk. And Alberto beats Swagger, with Ziggler cashing in and winning the title at WM. Thus setting up ADR vs. Dolph, or a 3 way.
the only other match I'm guessing they add to WM is Shield vs. Show/Shamus/Orton, which leads to some sort of battle between the SSO trio.
supposedly Ryback is turning heel after WM and feuding with Cena. I don't like the sound of it.
Ryback is a generic nothing without the crowd chanting Feed Me More.
