Re: John Cena (WHC) vs. Randy Orton (WWE Champion) - TLC MATCH FOR BOTH TITLES
Either way Cena vs Orton is closing TLC as well as RR. If there's a screwy finish, with each guy grabbing the other's belt, they will have the proper unification at the Rumble. If there is a definitive finish, then the loser gets his rematch at the Rumble. So in both ppvs, it will be the same main event.
Why I think there will be a screwy finish other than TLC being a B-PPV is because "unification" hasn't been mentioned. It could simply mean the winner holds both championships. So, if someone wins definitively at TLC, he'd hold both the belts but there would be no storyline explanation for unifying them.
If they swap it though, they can face off again at the Rumble in a winner take all, title unification match where they have enough time to build it. And then, the Rumble winner faces the Undisputed Champion at Mania.
