JBL versus Chris Jericho
I expect this to be leading to a WrestleMania match of sorts, and I think the first win in this rivalry will go to the returning JBL cheaply.
Predicted Winner: JBL

Career Threatening Match
Ric Flair versus MVP
Flair's career threatening match angle is going to at LEAST go to WrestleMania, so expect MVP to lose.
Predicted Winner: Ric Flair

WWE World Heavyweight Championship
Champion Edge versus Rey Mysterio
It's the Royal Rumble, and it's known for it's "filler" championship matches. That's what this is -- a filler.
Predicted Winner: Edge retains

WWE Championship
Champion Randy Orton versus Jeff Hardy
Now, this match has me a little uncertain about the usual Rumble filler theory. Because I've not seen a push like the one Hardy's getting ever. NORMALLY, in the WWE, during a fued like this, while one man gains massive momentum heading towards their match, the other person (in this case Orton) tends to get at LEAST one night where he stands with his hand raised. Because of how long this has gone on now, I would have expected that moment last week. Shockingly however, Hardy AGAIN gained the upper hand and took Orton out. So now I'm confused. Hardy's getting a push unlike anything I've seen in years. Not simply because he wins all the time, but because he's always gaining the upper hand on Orton, and anyone else thrown in his way! So I'm not so certain this match is a filler match, and it may lead to an interim champion. While the No Way Out rumors of the Elimination Chamber #1 Contender match state that both Orton and Hardy will be in the match, it would lead one to believe something will happen on a RAW that would make neither of them champion,... but we all know the card is subject to change. But Jeff Hardy might actually take the gold off Orton. I can't imagine how they can push anyone else more to take the belt from Orton if Hardy fails. So, unless it's a cheap disqualification on Orton's part...
Predicted Winner: Jeff Hardy

Royal Rumble Match
I've heard NOTHING this year about rumored people to win, but the way things are going, it's still early to even pick really. So I'll choose the three I think are most likely to win it, and of course, things could change to make it impossible for my picks to win, but here it is:
Predicted Winner: Triple H; Undertaker; Batista
