It seems WWE has changed the names of the Money in the Bank ladder matches for the upcoming pay-per-view on July 15th.
In the past, the two ladder matches have been divided up as Smackdown and Raw matches. According to WWE.com, they list Big Show as being the first participant in the "WWE Championship Money in the Bank Ladder Match."
This would indicate WWE plans to have two ladder matches branded by the two world titles with the winner of each match having a shot at that particular title.
