Honestly, the outcome of these matches seems pretty predictable. While I hope we get thrown some curve balls, this is how things seem likely to go.
For raw, we have orton in the main event for wrestlemania. It seems almost a given that cena will need to headline the raw side in some capacity, and at this point, cena seems the only viable option for orton to face. Does anyone really expect a raw main event being orton vs. kofi kingston? It's just not going to happen. So cena is likely to retain here. I would have guessed an outside possibility of jericho winning and a triple threat for wrestlemania, but instead it looks like jericho is going to be involved with...um, mickey rourke.
on smackdown, as of right now, we don't know who will be involved. But there's no way HHH is not going to headline wrestlemania. Right now, it also seems like his best bet for an opponent will be edge. so one of two things may happen. one is that edge also retains, and HHH somehow earns himself a title shot between no way out and wrestlemania (or somehow gets added to a mix). Or the other option could be vickie putting HHH through ridiculously difficult matches to qualify for the chamber, which he still manages to do, and then he wins the title at no way out. Then edge is the number one contender for wrestlemania.
Those are my predictions...I wouldn't mind being wrong, just for something different, but I guess we'll see.
