This has been released yesterday after the Nintendo Direct. Nothing special, but it should confirm that we're not seeing Skyward Sword HD any time soon. Not that anyone would expect this right now. I wonder, how this game will get ported to future systems, but maybe the rumored attachable controller parts of the NX also support motion controls. We'll see. A Skyward Sword HD will be easy to make concerning the graphics, you just have to scale them up and it will look great, but the controls might be a real obstacle.
Earlier I speculated about a potential Skyward Sword Month, where we get both the game on eShop and a Skyward Sword Picross at the same time, but that's probably off the table as well. If we're really getting a Skyward Sword Picross (or another Zelda Picross in general), the it probably will happen after the Twilight Princess Picross goes away on October 1st.
