Dragon Quest series creator Yuji Horii revealed, apparently on accident, that the 3DS releases of Dragon Quest VII and VIII will be released in western territories. Specifically, Horii announced a French localization for both titles while speaking at the Japan Expo in Paris; an English localization is therefore likely but has not been officially stated.
A separate announcement revealed that Dragon Quest VIII will include a new dungeon, along with a unique boss monster named Jahagaros. Little is known about the story behind said dungeon, save that monster has been sealed within and has been waiting for someone strong enough to reach it.
Dragon Quest VIII hits the 3DS in Japan on August 27.
