Rieko Kodama, who many of us know as one of the major players behind Phantasy Star, has a new RPG coming out next year. It's called 7th Dragon. Here's the site: http://dragon.sega.jp/
This is another Nintendo DS title. The visual style seems very different, but perhaps this may have a bit of Phantasy Star influence in it? I haven't looked at all of the material about yet, but it might be worth checking out if it comes overseas.
