Thanks, jiejie. I was under the mistaken impression that most non-Chinese ticket sales were going through CoSport (because, as you noted, they have links to so many country "sites"). I hadn't heard of Sportsworld. Is there any value in trying to follow these other country sales? I've had my friends in China try (unsuccessfully so far) to get me tickets, but I haven't tapped any friends in Europe. But if the situation is anything like CoSport, I can't really ask for folks to go to that kind of effort for me!
I suspect you are right about brokers/scalpers trying to get tickets, and that all of the CoSport allocations were pooled.
