I like the idea of Cena vs. Taker. I'd then back that up with Angle vs. Shawn Michaels. Where does The Big Show go? Probably somewhere with JBL.
Simon Dean vs. Viscera COULD be interesting. I hope we see a tag team come out of this. RAW needs new teams, and since my hopes that Rosey would join Simon have faded, I can always hope that Viscera & Simon can team for at least a while.
LOL, The Rock vs. Gene Snitsky would be gold! As long as Gene went over clean with his Baby-Killing Machine, "The Miscarriage" Pump Handle Slam. He really needs to name that. "I Snit on Your Grave" is the best I can come up with.
Rock vs. Orton would be good, and I can see the World Heavyweight Title being involved (if they put it on Orton). The Rock vs. Randy Orton, Triple H vs. Batista & Ric Flair vs. Mick Foley makes for a pretty decent card by itself. Adding Chris Benoit & Chris Jericho vs. Edge & Christian vs. Eugene & William Regal in a TLC Match as well as Maven vs. Shelton Benjamin for the IC Title, and RAW's side is shaping up nicely (IMO, anyways).
I doubt The Bashams will go back to OVW. I expect to see them win the WWE Tag Team Championship at the Royal Rumble.
I don't think The Big Show would be too vocal backstage (I'd have nor eal clue, though), because other reports have indicated he's really good to be around.
Anyway, here's what WrestleMania could shape into:
WWE Championship
The Undertaker vs. John Cena
Winner: John Cena via pinfall.

Randy Orton vs. The Rock

The Basham Brothers vs. Rhyno & Tajiri vs. Carlito Caribbean Cool & Jesus vs. Rey Mysterio & Rob Van Dam
Winners: Carlito Caribbean Cool & Jesus via pinfall.
WWE Intercontinental Championship

WWE United States Championship
Orlando Jordan vs. Charlie Haas

It's a little shaky, and its probably really far off, and would be way too clattered, but who knows?
