A couple of matches that I came up with were
Cena vs. HHH vs. Edge for the WWE Title- Maybe HHH can win a tournament to get the #1 contender spot by defeating Edge in the finals, but Edge reminds everyone of his MITB, so instead of taking the shot away from HHH, the GM adds Edge to the match.
Orton vs. Batista- WHC- A heel might finally win the Rumble and Orton can challenge Batista for the belt.
Shelton vs.HBK- I hope that the build up is done slow and well so this match can be really meaningful storywise, but I think it'll be awesome.
Kurt Angle vs. RVD- Hopefully RVD gets his well-deserved push when he gets back, and I would really like to see a match between him and Angle. Maybe they could revolve the match around an ECW invasion on RAW led by RVD (and maybe Heyman if he is the new GM), and Angle tries to defend RAW as a leader.
Hogan vs. Austin- I would like to see this match because it is a dream "Legend vs. Legend" match, and hopefully they are able to do it.
Undertaker vs. Mysterio- This one seems weird on paper, but when I was thinking about what to do with Rey, I realized that he has faced just about everyone on the SD roster and interacted with all of the big names, except the Undertaker (since his gimmick change at WM20). I think the match could be really good, if they build a story around it involving an evil heel Taker after his program w/Orton, and the usual underdog Mysterio. I know it doesn't bring Rey to his full potential in the ring, since Taker is a lot bigger and older, but I think that by him wrestling the Undertaker at Mania, it can bring a new main event/upper mid-card fued for Rey (and Taker)
That's all I came up with so far
