That title sounds an awful lot like a localized title for Fire Emblem: Mystery of the Emblem – Hero of Light and Shadow, an upcoming Fire Emblem remake slated for release next week in Japan. Perhaps, Nintendo is considering to release the Nintendo DS game overseas.
The magazine also has a bit on The Last Story in the games from Japan spread, albeit without any release information. Nintendo is publishing Mistwalker’s Wii RPG this year in Japan.
