WWE Championship contract Money in the Bank ladder match Money in the Bank 2012

This time board of directors have said that only former WWE Champions would be in this Money in the Bank ladder match. So as a result John Cena, 10 times WWE Champion but never been in a money in the Bank ladder match, the Big Show, who is dominating everywhere and his victory can be a big threat to WWE, Kane, who hasn't been the WWE Champion since 15 years but won Money in the Bank 2 years ago and cashed it in the same night and became the world heavyweight champion, and Chris Jericho, who invented Money in the Bank but haven't won any of them, would be competing in this match and this match can be remembered till decades if  all the men gave what they have to win this match.
