According to The Wrestling Observer, the following are rumored names for Money in the Bank contract ladder match at the Money in the Bank PPV:

Dean Ambrose
Big E.
Rob Van Dam
Bo Dallas
Bad News Barrett
Dolph Ziggler

If Ziggler and Barrett are not in the bout, it's likely the two will face off in an IC Title match at the PPV.

If thats the case then the only one i can see winning is Barrett

Fuck RVD off and put in Rusev.

I assume Ziggler will be doing a job for Wade at the PPV rather than either being in a match. They'll want a male singles title on the line outside of the main event, I think.

Other than that, it would be weird to me if they decide to have 7 men in one MITB match and 6 in the other.

^You forgot about Seth Rollins already being in the match.

I didn't forget I just didn't put it together.
