What? Professor Layton isn't even out yet, and you want more? Nintendo will give it to you. The final page of the instruction manual for Professor Layton and the Curious Village confirms that the next game in the series will come to the U.S.
In the Japanese version of the game, there's a secret password entry screen that can only be unlocked by playing the sequel, called Professor Layton And The Devil's Box in Japan.
That same feature is in the U.S. game, and the instruction manual specifically says that the password "will be revealed in the sequel," so take that as your official confirmation.
Professor Layton and the Curious Village will be available starting Sunday, February 10. If you're in New York City, head over to the Nintendo World store for the official launch party, from 1-3 PM. They'll have puzzle challenges where you can win a Cobalt/Black Nintendo DS, which launches the same day.
