In their official press statement, Nintendo states this:
Fire Emblem Fates: Two versions of the franchise’s new installment offer players an unprecedented choice: fight an opposing force or join the other side and try to make changes from within. For the first time in the series, players take on the role of the main character and command an army, while struggling to decide which path to follow: helping blood relatives or the family that raised him or her. The game is scheduled to launch in 2016.
Furthermore, poking around in their official E3 site reveals the two versions’ subtitles.
