I wouldn't mind voice acting but I'd like it if they all spoke like Midna... Because it adds a certain "another world-ish" feel to the game. You know Hyrule isn't the USA, they shouldn't speak english! The text would still be there as a "translation" of what the characters say. I agree with most people that Link should remain silent, exept for of course his grunts.
I also think they should give more options in the game about what you say to a character... You can decide about Link's personality by the way you answer the questions. Example, someone asks you if you need help, you can either chose yes politely, say yes without really wanting their help or refuse with an attitude. That would give more liberty about what kind of hero Link is. Some people could chose to make him arrogant/lone wolf or very kind/light hearted hero. It would also make a difference about how the NPC see Link. Think of all the possibilities!
