Atlus has announced that Etrian Odyssey and Mystery Dungeon is being localized into English, and the game will be released under the name “Etrian Mystery Dungeon” in North America. Play-Asia already has the game available for preorder for US$ 39.99, with a release date apparently scheduled for March 2015. The game was only revealed about a week ago, so it’s great to see the localization being announced already! It also bodes well for a possible localization of Etrian Odyssey V and Etrian Odyssey: Untold II.
EDIT: The official website can be found here: http://www.atlus.com/etrianmd/. Atlus states that the official release is scheduled for Spring 2015.
