Nintendo announced that they are planning to do a remaster of the Wind Waker in HD. According to their direct channel, the speaker said that the other zelda game that they have in development is going to take longer than expected due to what the Wii U would require them to develop in a zelda game. In the meantime they are treating us to this rather impressive remake if you are a Wind Waker fan. The updated graphics remind me of Skyward Sword a bit if you take a close look at the artwork in the screenshots.
