Jerry, I've been travelling out of China and so my ear is not planted to the ground right now. I'm not back in Beijing to massage contacts and snitches until mid-March. So, I'm also watching Cosport and there have been no more individual tickets put out there yet. The Chinese public Phase 2 payment deadline is looming in a few days, and I suspect that after that passes, BOCOG will release more tickets to the international community.

However, I think the prospect of seeing many (or any) more tickets to premier events like swimming, diving, gymnastics, etc. is fairly slim. Expect anything like that to go quickly, and that most of the additional tickets will be in less popular sports. I advise checking Cosport regularly (maybe even daily) to see status. On their home page, they also have an email notification request form, which can't hurt but I wouldn't depend only on Cosport promptness in lieu of your own proactive checking.

For Josanna: Artistic Gymnastics ends on August 19th and Swimming on the 17th (except for the 10 km long distance events on the 20th-21st), so you are limited in your opportunities to see these events anyway if you are coming over the last 9 days. Tickets for these will be very tough to get except on the secondary market. If you decide go that route, be very careful who you deal with. As for transportation from Shanghai onward, consider train or flight to a nearby city such as Tianjin and get transportation by car from Tianjin airport to Beijing, about 1.5 hours.
