The Spanish and Italian pages don't explicitly say the game will be in that language, but I'm hoping the lack of a "will be added via update" means they'll be ready to go day one and not that they won't be available at all.
For those unfamiliar, this is a fairly big deal as the last time Capcom made a non-English or Japanese translation was AA4, IIRC. (Professor Layton vs. Phoenix Wright had European languages, but that was an NoE gig.) Even the 3DS trilogy release was English and Japanese only I think despite European translations of the trilogy being used on the DS.
