Mr. Kennedy in 2007

Even before he got hurt in 2007,(and later popped for a Wellness Policy violation), were they really going to have Mr. Kennedy wait a year until Wrestle-Mania 24 in 2008 to cash in the Money In The Bank briefcase he won at W.M. 23, or did his injury cause him to have to drop the M.I.T.B. briefcase to Edge?  

I've always heard he was going to cash it in much sooner as a part of the aborted "Mr. McMahon's child" storyline.
