Rochette will definitely be at 2010 Worlds---all the Canadian skaters had to sign an agreement that if they made the Olympic team they would compete at Worlds.
If Yu-Na wins the OGM, I'm fairly sure she won't be at Worlds. Asada probably will be unless she wins the OGM (not that likely); if Ando wins a medal in Vancouver, I'd say chances are she won't be. But if one of Asada/Ando is out, that means Suzuki is in, so it's a draw.
Lepisto, Korpi, Kostner---definitely in. Not sure about Meier and Sebestyen.
Winning back 3 spots depends on whether Mirai can rotate all or most of her jumps and that she doesn't crumple under the pressure of a) her first Worlds and b) getting back 3 spots. If Mirai places decently in Vancouver (top 10) her chances of placing high enough for 3 spots are much improved.
