Yeah, this definitely points to him winning the WWE Championship and going on to defend it at Elimination Chamber when combined with several previous reports (like the one that states Rock's been under the impression he's winning the title and the only big problem was Rock can't do house shows). Personally, I don't like the idea of Rock winning, but part of that was due to me not believing he'd defend at the Chamber so it seems there'll be less to bitch at.
Also, since I am assuming he'll be wrestling at the Chamber, I fully predict he'll be wrestling in the Chamber match since it'll be the easiest way to promote him in a match he hardly has to wrestle in. Have him as the last entrant, and based off previous Chambers, that leaves him with ten minutes he'll have to wrestle (and they can always cut it down but it's less than that considering he'll probably get down time). And plus, there's no rule that says he needs to wrestle on the steel (or that he has to bump on it) if they want to be extra safe. And to be honest, I do want to see Rock wrestling in the Chamber, so at least this black cloud has a silver lining for me.
