Yep, it's time for the series to evolve. People have been expecting it since WW, and having yet another read-only game would just dock the series lower in the eyes of the general gaming world. I think it's time real emotion was put into the Zelda games. And not just the emotion that you're forced to make up yourself while reading text. Voices can express a character's sadness, anger, and traits way more than just a wall of text. Now you may want it to stay that way; you may just want to go along, making up personalities for yourself for every character in your own eyes, but that's not going to work for me, because I get sick of it.
And yeah, I know all of you are going to crawl into your depression corner and cry when someone talks and it doesn't sound like you "imagined" it would. Personally, I wouldn't care, seeing as I'm no good at making up emotions and voices for myself for a character, which is the only way anyone in Zelda can really be expressed outside of body language that's been reduced to eyes for the most part.
I want progress. For me right now, I play Zelda just for fun. Not for story, and not for emotion. If it ever wants to evolve beyond just "fun", it's going to have to start somewhere. Long overdue voices would be a good start. Or if it wants, it can stick with it's amazing game play and never be anything more to me, which I guess is fine seeing as I have Final Fantasy and Kingdom Hearts games for the other stuff.
