Oh god please no. The day they go the "all magic is merely advanced alien technology" route is the day I finally give up on this series. I don't care if Miyamoto's original idea was for Zelda to be science fiction, the further they stray from the high fantasy world of the original, the more disinterested I become.
I think that's a bad way to look at it. Magic is science that we just don't understand yet, there's always a base of reality even in a fictional world. As we go back into the series timeline, we can see what it truly is, and all evidence points to being some form of advance alien or lost civilization technology.
We know now that the Ocarina of Time's magical properties comes from a strange crystal, which even raw from the earth has strange alien symbols. Fi seems pretty much like an advance holographic AI (I'm guessing the crystal on the Master Sword serves as the projector and computer), there's dozen of little robots that existed hundreds of years before Skyward Sword that worked in a large mining factory, the time gate activates and acts like a sci-fi device. The Tower of the Gods in Wind Waker, a tower made by the Gods after the Great Flood, looks extremely technological as it's clearly based after the Atlantis legend, which many believe was a society with highly advance technology. Look at the patterns and symbols around the temple, how they glow sometimes and how strange and alien it seems, look at the ring around the boss room.
I've gotten gotten use to it, and it's becoming more and more blunt as the series moves on. Zelda U seems to continue this trend, Link's new arrow is being far more technical rather than magical. This is the way the series seems to be going, a mix of sci-fi and fantasy.
