I don't claim to know much about the Tibet situation, but I feel relieved knowing that the issue - and others involving the Chinese government - will be at the forefront of media coverage whenever the subject of the 2008 Beijing Olympics comes up. The IOC itself has warned that the great firewall of China should not affect journalists during the games, and throughout the torch relay the protestors have successfully subverted media coverage. It's going to be a fun summer.
(Compare the last link with the official web site's own report of the London relay. Oh, how sanitized the news can be.)
And the IOC can say all they want about journalists having free access, but I highly, highly doubt it's going to happen.
