Here is the confirmed matches:

WWE Heavyweight Championship
John Cena (c) vs. Umaga

WWE World Tag Team Championships
Team Rated RKO (c) vs. DeGeneration X

WWE Intercontinental Championship – Cage Match
Jeff Hardy (c) vs. Johnny Nitro

WWE Womens Championship
Mickie James (c) vs. Victoria

Ric Flair vs. Kenny Dykstra

Carlito vs. Chris Masters

Well here are my picks:
John Cena - I think WWE is going to continue to have him "beat the odds"
Team RKO - They just simply will win, or will lose via DQ, but keep the titles
Nitro - I love Jeff Hardy, but Nitro has shown he can perform
Mickie - WWE Womens belt really means nothing, but these are the only 2 that can wrestle.
Kenny - Kenny should be getting a huge push
Carlito - stick with the fan fav on this one
