Edge will be stripped for the title, so the match at the elimination chamber will be for the belt. Before the match, Big Show will be attacked by the corre (setting a corre/big show match at WM). His place in the contest is taken by Christian, that wins the match and becomes the new world champion.
At smackdown Edge invokes his rematch clause and make the match at WM a Triple Threat.
Thats the way I see it happening
