Here we have the latest trailer of The Legend of Zelda: Skyward Sword from this year's Game Developers Conference. It shows the precision sword control that the game has since it will be using the Wii Motionplus. As well as what looks to be parts of the actual dungeons that will be in the game.
Coming off of Twilight Princess' darker art style, Skyward Sword might look weird at first glance since it went with the opposite with bright colors. But the graphics do look very impressive and I believe the use of Motionplus for 1:1 sword movement will prove to have a more immersive experience.
