The Legend of Zelda: Twilight Princess HD includes a cheeky nod to the as-yet untitled new Legend of Zelda for Wii U.
Visit Castle Town's ultra-expensive store before it becomes Malo Mart and you'll notice Zelda Wii U screenshots featured as paintings on its walls.
Nothing new of Zelda Wii U is shown - the images are screenshots Nintendo has shown off before - but it's a nice nod to the mysterious, unreleased game.
Perhaps the paintings' presence in Twilight Princess HD is a nod to Zelda Wii U's place in the overall series timeline?
Nintendo has said very little of its upcoming all-new Wii U Zelda, other than the fact it would feature a large open world. It's widely-expected to release this Christmas, and may well receive a Twilight Princess-style dual-release on Wii U and Nintendo's NX console.
