During the reveal of their new IP Code Name: S.T.E.A.M. Nintendo developer Hitoshi Yamagami responded to a question about Shin Megami Tensei X Fire Emblem. When asked if development on the rarely mentioned Nintendo/Atlus crossover had slowed as a result of S.T.E.A.M. Yamagami said "We're right on schedule, but if I answer in any more detail I will lose my job, so please have mercy on me." SMT X FE was announced in January 2013 during a Nintendo Direct conference, but not much else has been said about the game.
SMT X FE is definitely one of my most anticipated games right now, but it does worry me how little I know about it. Hopefully Nintendo will do some kind of post E3 Direct and give us more information on some of the games that weren't brought up during E3.
