The card looks something like this so far...
World Heavyweight Champion Batista and WWE Champion John Cena vs King Booker and Finlay
Last Ride Match
The Undertaker vs Mr Kennedy
Kane vs MVP
And most likely...
WWE Tag Team Championship
Paul London and Brian Kendrick vs William Regal and Dave Taylor
United States Championship gimmick match
Chris Benoit vs Chavo Guerrero
what else is likely??
