If Korea's anything like Japan after Midori Ito, you bet it will. And I don't doubt Korea's cultivating its new crop of skaters right now. In fact, I think Yuna sponsors some of them (both male and female).
Yao Bin was motivated by his humilation at his own Worlds, so you gotta appreciate what he's done. Must be proud. I know I am. It's a shame that China didn't help new singles skaters after Chen Lu retired. If they did, I'm sure they'd be great.
Yes, I agree that you may see a Midori Ito situation with Korea. My impression with Korea (from a month-long visit on a cultural exchange last year) is that once they see a taste of success (whether it's in business, sports, or otherwise), they will cultivate it.
I really like Yao Bin. I could watch that NBC Olympics fluff about him over and over again. He just has this sense of humor and personality I love.
