This years Royal Rumble is truly a tough one to call.
There's John Cena, but I think he'll be having his rematch with Sheamus for the WWE title. Undertaker will be facing Batista again, too, so they won't be winning. Triple H And Shawn Michaels I think are out of the equation, too, since there's been many rumours about them facing off at Mania.
Looking at the current main eventers, there's a few that could win it. Orton could win it twice in a row, he's just as over as when he won it the first time. As long as he's facing someone other than Cena or Triple H at Mania, I'm happy.
Jericho has never won the Royal Rumble. Now that he's out of the tag title picture and off Raw, he could do with a main event push. Whether he's over enough to headline Wrestlemania is arguable, but we'd get a good match out of him if he was in the main event.
There are reports that Edge's recovery is well ahead of schedule. So, if he returned, won the Rumble and kept a light workload till Wrestlemania, like Cena did 2 years ago, that'd be pretty great. He'll no doubt be over enough to headline Mania when he returns. Hopefully he either makes a Rumble return or is a surprise entrant in an Elimination Chamber match.
Now, some of the younger superstars...
Kofi Kingston, the guy's red hot right now. If he could get a clean win over Orton some time between now and the Rumble, people will take him seriously as a contender. They'd need to build him up a bit more before Mania, but they could do it.
John Morrison is a possibility, since he just got out of the IC title picture and should be moving up to the main event now. But I think he's much more likely to end up winning MitB, cause it just fits Morrison. So yeah, he'll definately have a good showing in the Rumble, anyway.
CM Punk is the dark horse. He's still pretty damn over as a heel. He's still working in the upper midcard, but he's getting enough heat to warrant a decent main event push. Whether the guy can win the Rumble is totally up for debate, but we've seen him put on matches that are great, he could put on a good Mania main event if it was asked of him, especially if it was against Cena or someone.
People are talking about guys like Ted Dibiase or Drew McIntyre, but no way. Dibiase is nowhere near ready. If they had started pushing him as a face when he had that match with Orton, he might be ready by now. But they kept him as a heel jobber, so no such luck. And McIntyre was even ready to win the IC title, let alone win the Rumble.
