I totally agree with Rain's assessment.
Dance
All Navka/Kostomarov. I see almost no chance for anyone else to win, simply because the judges have made it crystal clear that N/K are the current Golden Children/Chosen Ones. Everyone else is skating for silver and bronze. My personal hopes lie with the French team.
Pairs
I agree it's between Shen/Zhao and Totmianina/Marinin. All the other pairs are a notch below those two teams. If Shen/Zhao can get and stay healthy, it could be a horse race--potentially very close. If the Chinese aren't healthy, Totmianina/Marinin will win easily.
Men
Despite his withdrawal from Worlds, Plushenko is still The Man, and everyone knows it. If he is healthy, I believe he will win--and win fairly easily at that. If he's not healthy, the field is wide open, with Lambiel and Weir the biggest threats in my opinion. Buttle and Joubert could also contend for gold. I see Lysacek, Lindemann, Li, Griazev, and Sandhu as medal threats, but not gold threats.
Ladies
No question: Irina is the favorite. However, I feel like this is the most unpredictable of the events. Irina has a clear edge in reputation and results, but her health is a big question mark. If Irina isn't skating well, I feel like the competition is wide open. It would not be shocking to see Michelle, Sasha, or Shizuka win gold. I think Fumie and Joannie are much, much longer shots, but it's not totally impossible to imagine them winning, either. Carolina is the real dark horse. The judges seem to like her, and more importantly, Carolina has shown the ability to bring her top game to the season's marquee event. Like Lu Chen in the 90s, Carolina tends to skate better at Worlds than she does anywhere else. If she can focus like that in Torino, who knows what could happen.
