I would think that they're gonna do to III what they did to I & II on the GBA. If not more. The DS has much more power than the GBA, so we can expect some good stuff here. Maybe new dungeons and an updated magic system, seeing as it's very similar to the magic system in I, or so I've heard.

Mmmmm. This pretty much seals the deal on me gettin' a DS. I can't wait!!! FFIII is the only one I've yet to play.
