I would much consider the battle for the gold medal : Kim Vs Osmond
Osmond could have be the «it» factor this year if she could have competed at NHK Trophy 2012 and she could have easily beat Mao Asada at the Grand Prix Final.
Look at those score at Skate Canada Challenge (5-9 december) that Kaetlyn Osmond earn:

Kaetlyn is definately able to win Sochi, she is very consistent and artistry
I dunno about winning Sochi, but I do think she's a rising star and will be a contender for a while. She's got big huge jumps, terrific transitions, good spins, skating skills, and interpretative ability. Could use a bit of polish and some of her expressions don't always fit the music, but yeah, I understand why she inspires optimism.
I think it's a little late for her to be gathering enough momentum to WIN in Sochi (we're talking about someone who didn't medal at last year's Junior Worlds...), but I wouldn't be shocked to see her on the Worlds podium next year. The one that's taking place in Canada.
Despite the fact that she didn't get an edge call at that competition, she needs to clean up her lutz and flip (got edge calls on both on the GP), and she could use a harder 3/3 than a 3T/3T.
She'll also need to be consistent! One good showing at the GP (contested by some, I think unfairly, but she could've done herself a favor by being clean in the FS) does not make a world contender. I look forward to seeing how she does in the future.
Kim has big PCS but her FS jump layout isn't even that ambitious, and she usually makes mistakes. I think it would be fairly easy for a Russian lady, or someone else, to outjump her enough to make up for the PCS deficit and win.
"Isn't even that ambitious"? What are you smoking?

She goes for the 3Lz/3T even though she could go for the easier 2A/3T. If hers isn't ambitious, what are programs like Akiko's, Mao's, and Ashley's (no 3/3 or 2A/3T), the top ladies at the GPF?
Is it the MOST ambitious? No, it is not. But I wouldn't consider a 6-triple program with a difficult 3/3 a program something that's not "even that ambitious".
That said, I think it's possible that at a competition Yu-Na gets outjumped by someone. If it's Liza though, Liza is
already out jumping others but isn't outscoring or defeating them. Adelina? Adelina is not outjumping anyone right now. Julia? Again, Julia outjumped many seniors already but still didn't win either of her GP events.
Yu-Na is in no way unbeatable but her chances in future competitions are looking good. Those 3/3s, lutzes, and the ability to do 3F and 3Lz help. Her experience having been under the greatest of pressures helps. it all helps. She's got a good chance, and that's all she needs. It's never going to be a 100% chance.
