Don't forget that it takes time to translate and add subtitles. And how long does it take Japanese movies to get released here? (and even then, usually just in very limited venues for very limited times... I still haven't seen live action Gatchaman, damnit!).
Translations (dubbing and subtitles) don't take that long... especially if it is a big budget movie.
Since it is being released in most countries on June 26th, it stands to reason that they have it ready in all those other languages (dubbed or subbed).
When I was borrowing a copy of the Frozen Bluray (I swear, it wasn't mine), I was amazed at how you could switch between the 8 or 9 languages throughout the movie... so I was entertaining myself by switching the languages, particularly when she was singing that main song.
I had expected it to just be subtitles, but to have it completely dubbed in so many languages (and this was just the European release), it mustn't have been that long to do.
(it was probably the only good thing I got out of that over-rated movie... hehehe)
