This past weekend, Nintendo of America registered three domain names.
Two of them were expected, but the last one was very surprising. They apparently registered Fire Emblem: Awakening for Nintendo 3DS. Looks like it may come to North America after all.
They registered Fire Emblem: Awakening, New Super Mario Bros. 2, and Pokedex 3D Pro.
