In an interview with Britain's The Guaridan, Zelda director Eiji Aonuma has given a none-too-subtle hint that the upcoming Wii entry in the series may feature, for the first real time in a Zelda game, flight.
"I have an eight-year-old son myself at home, and quite recently he started playing The Phantom Hourglass for DS, because when the software first hit the market he was too young" he says. "When he started playing with the boat, I told him: 'In the next Zelda, you are going to be able to ride on the train.' He answered: 'OK, Dad, first boat, and then train? Surely next time, Link is going to fly in the sky ... '"
Apparently having said that, he lets slip a big grin, before adding "I just don't know. If many people make many speculations ... some of them might be correct. Right now, I have to refrain from commenting on anything."
Now, this is Nintendo. He could just be messing with you/me. But with Twlight Princess having some sci-fi elements to it, and with Spirit Tracks featuring trains, the sight of a Hylian dirigible wouldn't be surprising in the slightest.
