The development team for Final Fantasy IV DS, beyond simply
having a blog, is opening itself up for a web-based question and answer session with us, the fans, starting now. This is all being facilitated by the
Square-Enix Members Blog, and you have to have an account to participate, but if you don't have one and don't feel like signing up, please feel free to ask your question right here and I'll be happy to submit it on your behalf.
They're a bit nebulous on the deadlines for submitting questions and the posting of the collection of answers, but I would imagine that all of this will be happening over the next couple weeks so that they can publish the final article no later than the North American release date of the DS game, which is still currently scheduled for July 22.
