Though Zelda made an appearance in one of the Wii U tech demos at E3, that was just an example of what a Zelda game could look like on Nintendo's new system. It's now been confirmed by Shigeru Miyamoto that Zelda will be coming to Wii U and Nintendo plan to create a "real" and "in-depth" HD Zelda game for it, that also utilizes the new controller features too.
Whilst speaking about the systems capabilities, Miyamoto revealed to Kotaku: "This is an HD system, our first HD system, and we want to create a real HD Zelda game for it. You will see a lot of these in-depth and deep experiences in terms of visual style. You will also see some play styles that are fun and interesting because of the play structure."
He also stated that there won't be any restrictions on developers to leverage the HD visuals in particular ways, explaining: "Even if you are using a simplier visual style it will still look very beautiful."
