Hopefully if there is a new F-Zero game, Nintendo will stream the F-Zero GP Legend dub just like Capcom streamed the MegaMan NT Warrior dub for it's new game release
There was an AMA with a 4kids employee along time ago. They even confirmed they only dubbed a certain amount of F-Zero GP Legend, but not the whole thing.
A heavily credible rumor that a new or port of an F-Zero game will be announced at the next Nintendo direct. Hopefully it will lead to the re-release of the 4kids F-Zero GP Legend English dub adaptation!
