Smackdown/World Heavyweight championship contract Money in the Bank ladder match 2012

Who ever would win this ladder match he will get a guaranteed World Heavyweight championship contract as he can challenge a champion for that championship any time and any where. This time there are only two wwe superstars who have experienced Money in the Bank ladder matches before, Christian and Cody Rhodes while other six have never and this would be interesting to see them competing in a Money in the Bank ladder match for the first time and even seeing them win.
