The first Super Famicom entry in the series is DS bound.
Nintendo updated the official Fire Emblem site yesterday with news that a new Fire Emblem game is coming to the Nintendo DS.
Entitled Fire Emblem: Monshou no Nazo Hiktari to Kage no Eiyuu in Japan, the game is a remake of the third entry in the series, which was 1994’s Fire Emblem: Monshou no Nazo.
One interesting piece of information is that the original Super Famicom version consisted of a remake of the original Fire Emblem, but seeing as the Nintendo DS has already seen a remake of that back in 2009, this new remake will likely focus on the "sequel" part of the Super Famicom title.
Not much else is known about the game, but a trailer can be seen at the official Fire Emblem site.
