I think the match will go Kennedy's way, just because of all the rumours about him vs Batista after WM. He seems due for a boost like this and is the most likely to win it. It will really give his career a shot in the arm and I think he has developed enough to be considered a title contender after Wrestlemania.
The Hardys aren't going to win it because they are permanently going to be stuck in the mid cards and I don't think they will win it because they just don't need or deserve it.
Edge has won it before and has had his time in the main event and I think he and Orton will have some program after WM so I don't think they will give it to him. He should provide some good spots in the match though, along with the Hardys, and he could save this match from being totally boring. I hope the injury doesn't affect his performance, but he is not going to win it which is a shame because that will end his WM streak.
Orton is a little tricky to decide if they are going to give it to him. I still think that they are holding a grudge against him for his past drug abuse and with the "latest" scandal, that may keep him from being pushed. I don't think he will be part of the big spots and it will be interesting to see how he goes in it. He should be involved with Edge after so I don't think they will give it to either of them for that.
A lot of people have been talking about how it is CM Punk's time. I find this bogus because 1: He is on ECW, a practically dead brand that has a champion involved in higher feuds, so the title is worthless and is also defended against anyone, every week. Winning an 8-man ladder match at Wrestlemania just to get a title that nearly everyone on that brand has had a shot at, and is not worth all the fuss anyway, seems like a reason why they won't give it to him. 2: With all the backstage issues that he has, why on Earth would the WWE give him a push like this one? It seems mindless that a guy as hated as Punk backstage would get a win like this. He is a longshot from winning it in my opinion, and I don't think he is worth winning it unless he switches brands, which I think he must do. Look for him to continue a program with the New Breed after Wrestlemania, not be the Mr Money in the Bank. The WWE will never put him over like this, so my expectations are not that high for him winning.
Finlay is the muscle in the match and won't do much other than hit people with the stick he carries. He isn't a main event guy on SD and he won't get the win here for sure. Stranger things have happened, but he isn't over enough, nor deserving enough of the win. I can't see Finlay winning this one at all, because you barely see him on SmackDown.
King Booker could have a chance in this thing, but again, I think he has had his run in the main event. He should be sort of de-pushed after WM and just slide back into the midcards. It will be interesting how he goes in this match, but I don't think he will be doing a lot of spots. I don't think he is really suited for the win and so he won't get it.
The match should be interesting but it won't save this wreck of a card. Should be match of the night if it just has a few spots here and there, but I think Kennedy will get the win because this is what launches good wrestlers who aren't getting their fair push and I think it should be Kennedy's night. The rest just don't seem to deserve, warrant or need the win and so I think Kennedy is the guy that's going over. Things could always change and with 8 people, who knows what could happen?
Winner: Mr Kennedy.
