^ I think the Main Event will tells us how the event will play out. WM produces two title change per year. The only exceptions was last year where three titles exchanged hands and WM 17 where 4 changed hands. So, what are the two logical title changes? Kalisto jumps out at me because they are trying to turn Ryback into a major heel. It does seem illogical to have three title matches all go to the current holders before a change for the World Heavyweight title.

I agree.
If the HIAC is the last match - that should indicate Reigns and Shane winning.
