It sucks, but there might still be a chance for it to hit Europe. I know the Hotel Dusk sequel did, so this one might, too.
But there's still hope for an American release. I don't remember where I found it, but they were asked and replied that they just don't have plans for releasing it for now, so they might release it later, who knows.
To be fair, AAI1 was one of the weakest AA games, along with Apollo Justice...
What's so bad about AAI?
I never got all the flak for Apollo Justice either. It doesn't hold up to most other games (except JFA, that one's terrible), sure, but it's still a solid entry with nice cases and amazing characters (like almost always). Kristoph is, especially, great.
