You should also be aware that even beyond any traditional trademark and cybersquatting concerns, the Ted Stevens Olympic and Amateur Sports Act affords special protection for the OLYMPIC mark to the United States Olympic Committee in U.S. enforcement actions (yes, this law was passed before Mr. Stevens was indicted).
Okay so I'm boned... I just came accross this thread and I happen to be building a Olympics information blog. I was hoping to make it badass, full of all the info people seek. http://www.london-2012-olympics.net
i think they're very good domain. just keep it. build link with them. wait 1-2 years.. and i'm sure you will be rich...
