In the latest issue of Famitsu, Level-5 honcho Akihiro Hino reveals the first bits of info about upcoming Professor Layton game.
Titled Professor Layton and the Miracle Mask, the game features an overhaul of the game system. The "miracle mask" is connected somehow to the mask worn by bad guy Death Call in Professor Layton and the Devil's Flute. The game's art seems to be set in a carnival.
Professor Layton and the Miracle Mask is scheduled for release in Japan sometime in fall 2010.
