First, even if you are disappointed about the new 3D Mario, you'll have to admit that it most probably will be a game of quality with a lot of creative ideas - the same formula used in any other Mario-centered game so far. Sure, it is not setting new standards like Mario 64 or Galaxy, but it isn't a "McDonald's kind of videogame" ^^
So considering, Nintendo plays it safe with this game, I would assume they play it safe with Zelda, too. That means, it'll keep the main ingredients and quality standard of the recent entries like Twilight Princess and Skyward Sword. I wouldn't bet too much on it looking like the demo we've seen in the last E3, but I wouldn't be surprised if it did!

You can play as an octopus, though!
