Adelina had the same case last year - not eligible for worlds, but went to WTT. So pretty surely Julia could go too.
And I don't get where people get that sense of "these skaters have to go or they'll be pemalized!" from? Definitly not from last years WTT.
Hanyu was injured last year and didn't compete, he seems to be even worse this year, so I'll doubt he'll have to go. Maybe he'd want to, but for now, I'm not really expecting him to be there. Especially since Japan has so many other great man... I'm not sure if Takahashi will go. Last season, it was a very good event for him, but this year he looks so exhausted. It might be another good opportunity for Mura, or if Kozuka is healthy again, he could make a little comeback here to show he's still someone to watch out for.
France will probably go with Joubert and Amodio, but mainly, I just don't know whom else they could send.
Chan and Reynolds looks reasonable for Canada too, and China will very likely send Song and Yan.
Russia should send Menshov, but I wouldn't expect Voronov to be there. Probably Kovtun, if he doesn't want to go, maybe it'll be Gachinski.
America I think should send Aaron, he's done very well for himself that season and doesn't look that exhausted to me. Farris would be the other best choice I think, it would be a great first showing against the top senior men.
For the ladies: I fear Suzuki will be left out and it will be Asada and Murakami to compete (although Mao skipped WTT last season too). China has Li and Zhang. I'd like to see Gao being allowed to skate here, but it will probably be Wagner and Gold.
The russian entries are a little harder to predict, but I guess Sotnikova will be there. Second one might be Lipnitskaya, to give her more experience. I'd like to see Tuktamysheva, but I guess Mishin won't like that.
For Canada, I'd like to see another one of the younger girls, like Daleman, next to Osmond, but maybe it will be Lacoste after all.
Meite will have to go for France, but that second spot...
