In Nintendo’s first Nintendo Direct for 2015, they started off with a megaton: a teaser for a brand new Fire Emblem title for the Nintendo 3DS.
As with most new announcements, details are scarce at the moment, although from the available footage, the graphics and gameplay are very similar to the previous entry, Fire Emblem: Awakening. This apparently includes the Dual System (Dual Strikes etc.) introduced in that game.
