People have been talking about "China Allows Access to English Wikipedia" at http://yro.slashdot.org/article.pl?sid=08/04/06/1643223
The communism party has been testing the partial lifting, mostly open to western visitors during the Olympic Game. Because the People Republic of China did promise the openness of the internet access to the western media, PRC will try best doing so for western media only, and this does not mean fully lifting the block to Wikipedia and alike.
A possible implementation may will be like this:
* The media center of the Game will has full access to the internet.
* Other internet access points given to the western media like those in hotels may have 100% to 90%
* Other access points in Beijing will have many blocked popular site open for the period of the Game.
* In most parts of China, the censorship and the internet terror activities by the communism party may remain almost the same.
So, PRC can keep the promise for the period, while keeping the censorship to most Chinese in the mainland China.
