Tokyo Game Show is a Japanese video game convention held in Japan yearly around September. This year, it's going to be held September 20th - 23rd. While this seems amazing and all, the only bad thing about it is that it doesn't focus on overseas, so it focuses on marketing in Japan. However, there may some games that will ship to all the countries, so don't get too disappointed. Sony and Nintendo will be there fo' sho', and I wouldn't be surprised if a new Mystery Dungeon game is released, but we'll soon see.
