Here it is. Be sure you're sitting in case you foul yourself. According to this Kotaku piece, Afrika will release in Japan on August 28, priced 5980 yen.
SCEE's already said this isn't going to make it to Europe, so you'd better get importing.
Provided you can stand the tension of waiting for the post. You could spare yourself the pain by flying to Japan on August 27, sitting outside a game shop and waiting for it to open, buying a PS3, getting a hotel room a week, taking thousands of pictures of fucking zebras, realising how futile the entire exercise was, how dull the game actually is, then jumping off the Tokyo bridge in self-disgust.
