Jeuxvideo reports on some interesting comments from Nintendo UK execs indicating that import favorite Osu! Tatakae! Ouendan may well be headed for publication in Europe.
The title is extremely Japanese; the song list consists entirely of Japanese hits and the mangas, while extremely funny to the otaku set, are also steeped deeply into Japanese culture. A localization of the title might still retain these elements, but it seems more likely we would see Ouendan remade with European songs and predicaments. We'll see what comes of this, if anything.
