This first video shows off never before seen footage of the Hyrule Field from the Ocarina of Time remake for the Nintendo 3DS (which has a release date after the summer). It shows off how amazing the graphics look in this Zelda 64 remake, proving this game will be a must have for any Legend of Zelda fan. (Skip to about 2:00 in to check out the new footage)
Next up is brand new video of Link travelling through the Kokiri Forest, the Great Deki Tree and fighting Gohma.
Ocarina of Time 3D isn't the only upcoming new Zelda title, Skyward Sword (for the Wii) is in it's final stages of development and should release sometime this year (also after E3 2011).
