They never made the announcement yesterday. Teachers at my school have been saying that the country might be about to adopt some kind of Chinese-style capitalism.
From the Impudent Observer:
Any attempt to determine what is happening at the government level in North Korea is an adventure in speculation and mystery. There are reports that some sort of “an announcement of important information will be made on October 20.” Rumors concerning the meaning of the announcement range anywhere from the illness of North Korean leader Kim Jong-il to a possible military coup to take over the government. Or, it can be nothing more than an announcement about Kim Jong-il visiting a flower plant. North Korean diplomats reportedly have been told not to leave their posts and await news from the homeland.
