The Legend of Zelda: Skyward Sword wasn't the only Zelda announcement at this year's E3. Nintendo of America's twitter account confirmed rumors that The Legend of Zelda: Ocarina of Time would be the next game to go 3D on Nintendo's new handheld, the 3DS.
The Legend of Zelda: Ocarina of Time was originally released for the N64 in 1998 and has since been released for the GameCube and Virtual Console. If you plan on getting the 3DS, then hey, why not buy it for a fourth time?
No price point or release date has been set. We do have a cool photo gallery of Link and Epona in action though: Legend of Zelda: Ocarina of Time 3D photo gallery.
