No, I don't think so.
The organizers probably set up the ticket system based on past experience rather than taking into account the local peculiarities of South Africa (specifically buying habits, level of Internet access and access to bank cards). It appears they've corrected that plenty in advance.
When I was putting in my application for tickets, there were sections of the stadiums (the cheapest seats behind goal) that were marked off for local supporters. I'm sure there's a desire to see South Africans participate.
I saw this article yesterday and I found it interesting that the locals are more interested in the England game than in seeing S. Africa play! Hope that doesn't reduce my chances of getting US v England ticket!
