Re: It's pretty clear who is going to win the RR
It's an assumption to think Rock v Cena will headline WM 29. I think it's very likely Rock's not being booked to win at the Rumble and they're actually setting up Rock v Lesnar.
From there the Rumble can go 2 ways. John Cena, Undertaker. The other guy wins the belt at EC.
I wouldn't bet on Ryback. Mark Henry or Big Show should be his ideal opponent. It's too early to put the belt on him and putting him on Smackdown is just duplicating another Sheamus.
Sheamus v Orton should be written in black marker as Smackdown's Main Event at Mania.
