I just watched Hanyu's SP at Junior worlds and he seems to have a great future ahead of him! He had a mistake on his combo and some of his spins were uncentered (but great positions and fast ) but his 3a is huge and gorgeous and he has great speed and expression on the ice. He reminds me a lot of a young Kozuka or Dai. I think he will be a threat in Sochi, considering he is only 15 now and that good!
His program is also enjoyable to watch,and don't forget the fact that he is so cute. lol
Most of that entire of skaters in the second to last flight at the Olympics seem well positioned to challenge for the podium in 2014. The main skaters "missing" would seem to be Rippon, Miner, Hanyu and Song
