Eiji Aonuma, producer of The Legend of Zelda: Skyward Sword has revealed to The Guardian that the Zelda team had a bunch of interesting ideas that didn’t make it into the final version of The Legend of Zelda: Skyward Sword but may used in Zelda Wii U.
“We had many ideas for new abilities in Skyward Sword. Some of them didn’t work and so we abandoned them. Some of them, though, we’re keeping. Even though we couldn’t make them work in this game, we felt they’re still good ideas. Maybe we can make them work on the Wii-U. It’s possible you might see them in another game we make in this series.”
