Link shouldn't get text or voice acting. That's fine if other people get voices in the game but Link doesn't need one. His answers/replies are interpreted by the player. It's a good style. Not only that but the game doesn't require a bunch of dialogue and I hope they leave it that way. It's a adventure game and gameplay/dungeon crawling is what its all about. Link is about getting down to business.
He should however re-nact his tales like Mario does in SMRPG when talking to people, now that would be awesome.
