Do I want voice acting? Yes. With the right voice actors, it can be very pleasing to hear. Not everyone would want it obviously so the option to turn it on and off would be nice. I'd settle for something like Rune Factory has, where not every line of dialogue has full voice acting, just some of them, and some standard, base lines are said when you initiate conversations.
So, do I want voice acting? Yes. But do I think Nintendo will ever put full voice acting in a Zelda game? Hell no. I don't think they're ever going to do that. The voiced narration in Hyrule Warriors is probably the closest we're ever going to come.
