Some of those high-ranked SA skaters (the Japanese: Oda, Asadas and Ando) train in the US or Canada, so it wouldn't be that much of a biggie to go to wherever Campbell's is being held. The Canadians (Buttle, Sandhu, Rochette) are close by, too.

I'm not sure about Lambiel, though. There were reports that he had re-injured himself, and some of the COI reviews mentioned that he was having problems both jumping and spinning. He may want to go back home and rest up after the Tour and try to heal his knee.
