Not all. The first ones. Not disproven.

It's all about cost. Nintendo doesn't want to spend the money on something like that which would cost millions.

There is no random identifier. They don't carry onto "any other games" because no other games did those things first. You can't have two first motion controlled launch title Wii Zelda games. You can't have two first 3D open world adventure games. I guess the sales Majora's Mask and Twilight Princess for the GCN aren't "realistic" or "dark," because such "selling factors" did not carry over into those games, right?

Random identifier. Give me a break.

Link doesn't even have any dialogue at all to begin with, so him talking would be kind of odd. However I wouldn't mind if the other characters talked.

Schreier: You've talked a lot about shaking up the series traditions, and kinda changing things for Zelda in some big ways. For either Hyrule Warriors or future Zelda games like the one you just announced, would you ever consider giving Link voice acting and a personality?

Aonuma: Actually the voice issue is a little bit tricky. We could just make him talk, we could just give him a voice and have him speak, but does that add to how fun the game is? Does that add to the experience? It might actually just make it the same as a lot of other games. By not having him talk, it kinda lowers the hurdle for the player to really feel attached to Link, so that's something that I'm still having to think about.

Schreier: Is it something that you've ever actually experimented with, or made a prototype or anything like that?

Aonuma: (laughter) There are actually a series of videos called Nyan Nyan Mario Time, that are only in Japanese. In those videos, Link was talking, and not only was the actions and the voice a little bit strange, but it just felt strange overall.

Schreier: Why did it feel strange?

Aonuma: (laughter) Link doesn't talk yet, but if he did, he probably wouldn't sound like this.

Aonuma: But you know, in the same way that I have a strong sense for the way Link should sound, I think everybody has a sense for how their Link sounds. And Tecmo Koei I think they agree with me because they opted not to make Link have a voice in Hyrule Warriors either.

Schreier: Do the other characters? If I play as Zelda will she talk in the game?

Aonuma: They just do the "ahhh" sound. This is actually the first Warriors game where characters don't talk.

Wasn't that difficult to do... -___-

You're right. I'll do it next time I post an article!

I don't mind, I like to give silly voices to everything with my little brother as we play :P

I'd like to see the other characters talk, but Link should remain a silent protagonist.

Half-Life/Portal is an example of another series with an excellent setting and pre-determined characters whose protagonist is a silent one. The story in that, like the Legend of Zelda series, is not "bad" and the overwhelming majority of gamers seem to disagree with your assessment. 

Not every game needs voice acting. Keep it out of my Zelda, please.
