Bravely Second is coming out in Japan in April. It's just that they're hasn't been any word of it leaving Japan yet, although there has been some teasing from the producer. But, seeing Bravely Default's success in NA and Europe, a localization is probably locked in. If I had to guess an estimated date for an international release would most likely be in Fall at the earliest, with Jan 2016 at the latest.
Nice! I've been contemplating if I should get a n3DS myself. I'm not too keen on being limited on the XL version though.
