Okay just as Artefact said, it's not the end of the world. EOCS isn't part of the government, it's just a self regulation group. There are others, and what we can expect is for some of those under EOCS to shift to other review boards in order to publish their games. The amount might diminish but it will not vanish altogether. Besides, doujin soft aren't covered by boards like this.
Sorry for helping spread the hysteria.
