Honestly, the end of the Zelda series it really far away. As long as the series makes money and there's people like us, Nintendo is going to keep doing it, even if that means that we are going to see the 50th saga on the series. You want Zelda to end, then stop buying it and you'll see how it disapear. But that's something I'm not going to do for sure, as long as either Miyamoto or Aonuma are still alive, or maybe Aonuma finds a great succesor as Miyamoto found one in him (Aonuma).
