I think the WWE Championship MITB match will be won by Daniel Bryan or Randy Orton.
With what's going on between those 2 right now you can just see it coming down to them as the final 2 battling it out for the case.
The WHC MIB match is very difficult to call.
None of the participants are THAT over at the moment, and on top of that, they're all heels (it's going to be interesting to see how the crowd will react to this match).
Barrett isn't very over.
Swagger's messed up with his DUI
Sandow is over but I can't see him winning it
Fandango I'd give the least chance to of winning it.
Rhodes has gone cold
Ambrose is over but is the US champ, so can't see him winning it
Cesaro again I'm not sure on.
I'd have to go and say that Barrett, Cesaro and Rhodes are my top picks. Barrett could use the boost since he's gone very flat. Cesaro with his new pairing with Colter could be an interesting winner (with Swagger back, that would be interesting to see how it works out). And Rhodes I can see winning with the crowd getting behind him thus turning him face. Rhodes Scholars needs to end, fast, and Rhodes winning and going face would be a great way to build him up.
Here's another interesting thought though; Dean Ambrose. What if... The Shield attack at some point in the match and help Ambrose win the briefcase? Tag titles, US title and the WWE title MITB case in The Shield's possession? A pretty interesting scenario IMO.
