I'll make a prediction: Three years from now, most South Africans will have immigrated to other rugby-playing countries (due to worsening internal politics in South Africa), and assuming that the majority will move to Australia or New Zealand, it will be one of those two countries that will take it.
Or, if the number of South Africans here in Canada continues to grow at the rate that it has been, I would not put it past Canada to score big in the next World Cup either (Wooh-hooh! Go Canada, go!)
