I personally like it that there's no voice acting. Not trying to be a purist or anything, but it just fascinates me how the characters in Zelda can be so expressive and funny all through one simple noise or phrase, like the pawnshop owners "Hiyeee", or those two twin dancers hilarious angry grunt. I just can't imagine giving that up for regular voice acting, you can get that in any other game, it's one of the many things that make Zelda so unique. I love this Mr. Bean-like charm about Zelda, with every game it just excites me wondering how each character will sound.
Although I'll admit, it was kinda cool hearing Link talk a little in WW. When I heard Link tell the little statue to "COME ON!" I almost had a heart attack hearing Link not only say an actual word, but an entire phrase too, I loved it. I think the new game might just need some voices though, the goofy noises might be a little silly for this new Zelda, unless maybe they make each characters noise more serious sounding, yet still as expressive. Whatever they do, I'll keep an open mind about it.
