Dark Match Jobber
We'll obviously see the Rumble match, headlined by all the big stars, with either Cena or Batista winning, setting up their match at 'Mania.
I'd guess the SD main event would be something along the lines of Taker v. Punk, simply because there's no one else heavily involved in the main event scene. I don't see Jericho going from his current program as tag champ, to a feud with Big Show, to a title match Royal Rumble happening so quickly.
The RAW main event will most likely be Orton v. HHH or HBK, if I'm correct about Cena being in the Rumble. It's about time the damn feud between HHH and Orton ends, and no better time than at the Rumble, ensuring that we don't get them facing each other again at 'Mania. If it's not HHH, I don't see anyone else but HBK stepping into the main event so easily.
Batista will have a match with HHH & CM Punk. That'd be a nice III Threat.
They have to put Taker up against someone who we don't know if he'll win or not. Being that it's Mania, it should be Cena.
If Edge returns at that time, he will face Jericho @ Mania, but if he returns sooner & gets Jericho at No Way Out, he'll face Orton.
Orton's match will depend on Edge's return. If Edge faces Y2J, Orton will most likely face Legacy.
