Despite being Eiji Aonuma's first major Zelda project that he ran, it appears Eiji Aonuma wasn't really that keen on making a 3D version, even with Ocarina of Time 3D on the table. However, Miyamoto was rather insistent it happen, practically demanding Eiji Aonuma to make it happen. In the end, everything worked out and not only was Miyamoto happy, so were the fans and Eiji Aonuma ended up having a good time.
Bad news for TOTK fans, as it now appears unlikely we'll get DLC if comments by the game's producer are anything to go by.
