Who is Zelda Williams, you may ask? Why, she's the daughter of Robin Williams, and yes, she was named after the Nintendo princess. That Robin was such a video game nut isn't news to me, rather that his daughter somehow came out looking that hot when he himself is a hairy ape absolutely is.
Anyway, why the secrecy behind this particular shoot? If it was for a television commercial, Nintendo probably would have just said so. Given Zelda's involvement, it safe to assume that it might be related to the Zelda series -- we still have Skyward Sword and Ocarina of Time 3D down the pipeline, after all. On top of that, the series' 25th anniversary is around the corner.
Maybe we'll learn what the deal is come E3. In the meantime, I have to go look up photos of a certain aged comedian's daughter on the Internet. Shoo.
