No, I don't really think there is any point right now--everybody all over the world is in the same boat, BOCOG just won't release enough tickets. The local Chinese are in even worse shape, due to overwhelming demand layered on a huge demographic. And for some events like swimming, there isn't any amount of ticket release that would satisfy demand. There is supposed to be a Chinese Phase 3 sale starting this month, format yet to be announced. I suspect the Chinese are unlikely to release (m)any more tickets to international agents. After the Chinese Phase 3 sale has subsided, any remaining unsold tickets will go to central booking offices and/or venues to be sold in real-time. My guess is this last-minute sale will not happen until after all tickets have been printed and sent out worldwide to fulfill confirmed bookings--probably late July. Same for any returns coming back from sponsors and other organizations. Cosport, Sportsworld, etc will have offices set up to distribute any remaining tickets from their allocations, but I don't expect to see much out of that. Anyone who is planning on being in Beijing a couple of weeks in advance might have an opportunity to grab some last minute available tickets directly from BOCOG, but you'd be taking a chance. More than previous Games, I think a large number of events will be sold out before the show even begins.

Depending on your cash reserves vs sports desire, you may be forced to the secondary market either while you are in the USA, or wait until you get to Beijing. If you decide to wait until Beijing, try to use the intervening months to make contacts and queries. Some of us have quite a few extra tickets but need to get through the Chinese Phase 3 before finalizing our Use vs Dispose ticket categories.
