Matter of fact, the whole point of Miyamoto bringing Aonuma onboard as his protegé was to provide another hand at the tiller, a successor to take over the franchise when he ultimately decides to call it a day at Nintendo.

And so on, ad infinitum -- Aonuma can then hand off the reins to whomever he decides is most appropriate, to boot.

And most folks were plenty satisfied with Aonuma's work on The Wind Waker and Twilight Princess, which is proof right there that Miyamoto doesn't need to be intimately involved in each new Zelda game for the series to thrive in the future.
