Might the Sheikah appear in Zelda: Skyward Sword?

The image above is a snapshot of the latest The Legend of Zelda: Skyward Sword trailer. As you can see, the eye of the Sheikah made an appearance in the video, though it’s a bit hidden. This doesn’t necessarily confirm that the Sheikah will be a part of Skyward Sword’s story, but it surely makes things more interesting.
