I can see this one stealing the show. And I can see Rhodes winning the briefcase, as with it he'll be ready to feud with some of the big guys like Orton, Goldust ect. and then become even more stronger in terms of his character and credibility. Sandow needs high-profile feuds to make us believe in him, really.
One way they could put the briefcase on the line would be if Cody still has the original briefcase's contract. Sandow comes out and has a new briefcase (and contract), revealing that he was able to get the board of directors to get him a new one. Cody, however, claims that he found a loophole in the MITB contract and this means he can claim the contract he has now. Vickie comes out and says that Cody has just outsmarted the board of directors, and tells Cody that he has the match. Cody vs Damien, for the one MITB briefcase. Damien, however, uses his wits to get Cody into a gauntlet match for the night, and claims that the board of directors aren't and won't be happy with Cody, who ends up winning the gaunlet match and tells Damien that he doesn't care, and will win the new MITB briefcase at Summerslam.
