Square Enix announced the US version of Final Fantasy III for NDS will be released on November 14, 2006; while the classic Final Fantasy V Advance for GBA will be released on November 6.
I think the DS is cool, and same with final fantasy. This title (FF III) looked a little lack luster to me though. Of corse I can't say for sure untill I play it, but that's how I felt looking at the previews.
