I want a really big, vibrant, alive Zelda in a world that is much more revisitable than that of Skyward Sword, and makes much more sense than that of Twilight Princess.
But saying that, I don't find myself wanting huge RPG size worlds, like Skyrim or Xenoblade. As much as I love those, they're all about scale and would struggle to capture the Zelda "magic".
And I don't find myself wanting voice acting of any kind either. It's just not necessary in the Zelda universe. It's not a case of a modern choice, it's a stylistic choice. That gentle "badum" when you hit A after a segment of conversation creates atmosphere enough for me.
