According to an interview of IGN with Eiji Aonuma and Shigeru Miyamoto, Twilight Princess could possibly be the last Zelda on the Wii. In fact, they didn't even start developing a new Zelda game, but they're pretty much still planning.
Here are some quotes:
Q: Supposing you do make another Wii Zelda game, are you hoping to have one-to-one sword control in the game?
A: Would you like that? We're still fleshing things out, so I'm more than happy to hear comments from everyone.Q: Can you speculate at all about how many years it will take before the next Wii Zelda is out?
A: Actually, I've been speaking with Miyamoto about allowing developers enough time to creating something really quality. Just how long that takes depends on the project.and a few quotes from Aussie-Nintendo.com (dunno where Miyamoto is supposed to have said this)Q: Have you thought at all about setting the game in another setting?
A: I've thought about things like, "What if we sent Link to the contemporary world? How would he react? Or what if he was dropped into a WWII setting?" I've imagined all these ideas, but how these ideas might become a game, I still don't know yet.
Regardless, should a new Zelda game get the greenlight for Wii, it'll have to be something of quality again, Aonuma said. "I've been speaking with Miyamoto about allowing developers enough time to creating something really quality. Just how long that takes depends on the project," he explained.Shigeru Miyamoto offered his thoughts, and said, "It's really hard to say because we've never had a Zelda that's appeared so early in the life cycle of the system, so it's definitely possible that there would be another Zelda on Wii. Of course, the challenge is that typically a Zelda game is something that takes three years to develop, so we'll just have to wait and see."Sources:Of course, Zelda fans will have Phantom Hourglass in their hands on the Nintendo DS later this year, and the good news for the Big N is that it's been performing very well in Japan. "The Phantom Hourglass has been released in Japan and reception has been very, very positive," said Aonuma. "We've actually been able to receive feedback from the users and we'll definitely take all of those comments into consideration when creating the next Zelda, whether it be for Wii or DS."
So what do you think? Will there really be no Zelda Wii game? I think there will be a Zelda Wii title, every Nintendo Console with potential had it's own Zelda Title. And Zelda TP was a Gamecube game in the first place as mentioned more than once. But having to wait three more years? Patience... I need patience... ARGH!
