Just because I can...
Here's an early route spec based on some fact and the following rampant speculation...
1. I don't think they'd get that close to Antarctica just for kicks. Tours and cruises go to Antarctica all the time -- I think they'll go for it.
2. And Jo-burg is listed just because it's the most likely city of entry into S. Africa.
So there ya go...take it FWIW as the first route spec of the new season.
