At its digital-only E3 keynote this morning, Nintendo provided the best look yet at the next entry in the Legend of Zelda series. Not only does the Wii U game sport a slick new high definition art style, but it will also be the first in the series to provide an open world to explore. According to the developers, that means that you'll be able to embark on adventures in a much less linear fashion compared to the more structured games of the past.  "This is a clean break from the conventions of past games in the Zelda series," says producer Eiji Aonuma, "where you had to follow a set path and play through the scenario in the right order." The game was first revealed in 2013. You can check out the teaser in the video above, while the game itself is expected to launch in 2015.
