Pretty much proves the point there's no such thing as a dead franchise to Nintendo outside of some one shot really obscure titles. Some of the games might take long vacations, but if they can find a dev willing to do it, the series will eventually get a new installment. Yeah F-Zero's lack of polarity from the last games hurts it's chances from Nintendo making one of their major studio's to make a new one, but if they can find the right 3rd party to do it, it'll happen.
