This information comes via a Neo-Gaf post that stemmed from an article in Chronic'Art magazine. The post says that this title not unlike StarFox 2: Lylat Wars (a canned StarFox sequel from back in the SNES days) will be shown off during Nintendo's media briefing. Apparently this is a title Mr. Miyamoto has wanted to make since back in the day of the SNES, and he feels the DS is a perfect place for it. I will keep this in the rumor section for now, but for any of you that want to (and can) tackle the translation of the Chronic' Art article, you can find it HERE.
