Personally, I don't think Cipher will see an international release because the card game is only based on Fire Emblem. If it were like a card game with multiple Nintendo series, then it would have better chances of being released outside of Japan. Fire Emblem wasn't THAT popular until Awakening so a lot of the new fans won't know most of the characters cipher has to offer. Anything is possible, but it's not very likely. You can always hope though because hope will never die!
