"Currently Nintendo has yet to have confirmed a release date for either games. The Legend of Zelda: Spirit Tracks is set to release sometime in 2009, and Miyamoto has said that he hopes Zelda Wii will be released in 2010, though the likelihood of this happening is slim." Yeah, this is mostly because Shigiru Miyamoto is kind of a perfectionist, and has been known to delay (or even fully cancel) projects that weren't up to his standards. That's why Ocarina of Time didn't come out right after the N64, because they kept re-doing it.
