I'd just like to remind people that when responding to spoilers please post a warning, or just wait until the show airs so the people who don't want the results can avoid them.
Having read them though, it seems clear there's only 3 possible MITB winners this year, Punk again, MVP, or a participant who hasn't been officially entered yet. I think of that 3, I'd whittle it down to only two (MVP, or our unnamed man). I could see doing it with Punk again, but probably only if I want him to lose in a competitive bout and perhaps do it as he loses in Chicago where he's always managed to pull out big wins and he just snaps and turns heel. But I'm not sure that route is best to be honest, MVP is getting momentum back, and the unnamed guy I think is also got some momentum with him and there's some interesting and varied directions you can go there. I'm not sure how the match will come off as a whole (since you've got some guys who are good for this sort of match, and couple who aren't), but we do have three pretty equal candidates to go with here at the finish, all guys who could use that break out push and if not set up to fail could make the most of that. That's what I expect out of this sort of bout.
