Check out some of the most interesting games that are currently not slated for release outside of Japan. (3DS, Bravely Default: Flying Fairy, E.X. Troopers, Project X Zone, PS3, Tokyo Game Show)
But I never knew Bravely Default had no localization date o_O
It takes money to localize because it takes time and effort and work not just translation.
If they would localize more with a limited release they would sell more.
