Nope, same thing happened with Surging Aura for the Mega Drive, but this one is likely number two on the list. Though I think some Famicom RPGs (Hokuto no Ken 3?) got translated into Spanish too, as of late.
Either way, good to see it done, I'll probably give this one a go! Been interested in this game for a while, and my Spanish is better than my Japanese. Thanks for your hard work guys!
If I remember clearly, the DS version of Ni No Kuni also came out in Spanish before it did in English. But in the end, I ended up not playing any of both versions, due to lack of time. It's a pity, because perhaps I'll end up not playing this one as well, because lately I have lost much of the interest I had for the Star Ocean saga in the past (I was quite hyped when the project was announced in the AGTP site some years ago but, as time passed, my interest in this game faded gradually). Nevertheless, I want to thank the translation group for his efforts into bringing this game to the West (I'm a native Spanish speaker) and I'm sure it will be available in English shortly.
Oh,by the way: if there are non Spanish native people here trying to play this version and need any help trying to understand some sentence, expression, idiom, etc, just PM me and I'll gladly offer help if I can
