HHH will be the 7th man I think. Sheamus and HHH will have some sort of interaction leading to a survivor series match against each other, Team HHH vs Team Sheamus, then end the feud at TLC in a chair match or something like that.
I think that Raw will win this year. Nexus will interfere (they have to somewhere, and it wont be the Barrett v Orton match) and help Raw (coz they are on Raw) to win the match. They take down Raw after the match, leading to a match at Survivor Series maybe?
