I think someone like Ryback is going to win because Cody Rhodes currently doesn't have a feud other than his back and forth matches with Santino, which are clearly fillers. Funk man is a RAW guy and is a face, so it won't be a face on face match. Brodus Clay hasn't lost a match since he's came as the Funk man, so I doubt they'd give the strap to him, also people are getting bored of him. I personally have never liked him, anyway.
Ryback had his own video package this SmackDown, so to me it seems like they're building him up and people are liking this guy. He does have a great move-set and he's a SmackDown up-coming face, so to me it seems like he's a reasonable feud for Cody Rhodes. This would also mean Ryback could come on RAW, too.
I'm aware that they can come on any brand type of thing, it wouldn't matter if Funk man won because he can come on SmackDown, I'm aware. However, I'm sure they'd want someone to feud Cody for the IC title since Santino can have a feud with a bunch of guys and Cody Rhodes is pretty limited since he's on SmackDown and is in touching distance of the main-event.
