“The world of Hyrule has been reborn in a highly realistic stereoscopic vision, which will feature a new story and new puzzles to be solved. The development for the successor of The Legend of Zelda: A Link to the Past is going smoothly, so, please look forward to
The day we’ll be seeing the successor is still further ahead, but for those of you who wish to contribute or show your support, please comment on the Wii U The Legend of Zelda series community [on Miiverse].” - Eiji Aonuma
Aonuma seemed to hint that the idea of taking a 2D Zelda and making it 3D is something Nintendo has been toying with for awhile. This was a goal the team has been working on making a reality since 2011.
