Nintendo has revealed that another entry in the Fire Emblem series will be coming to the 3DS, but unfortunately that's about all they revealed, aside from a tasty tidbit from Nintendo's president, Satoru Iwata, who said that your choices in the game will affect the world much more than they have in previous entries.
In the trailer, it looks like the new Fire Emblem has taken several cues from the excellent previous entry, Awakening. They can take as many cues from Awakening as they like, as far as I'm concerned; that remains one of the best titles on the system.
The trailer also has some really cool pre-rendered stuff to give us a bit of the world. Check it out for yourself below.
