The Legend of Zelda: Skyward Sword is a pretty massive game, so it's no surprise that developing the game took five years. In the final chapter of Iwata Asks, director Hidemaro Fujibayashi hopes for a shorter period before the series' next entry.
While it's not clear if he and producer Eiji Aonuma are referring to a Wii U or 3DS Zelda game, the following quote provides some insight into the franchise's future:
"For the next one, if we will build on the methods we established this time, we might end up getting into a rut," Aonuma says. Fujibayashi—whose role as director on Skyward Sword marks a first for him after serving as sub-director on Phantom Hourglass—agrees, calling the hurdles the next Zelda game will have to overcome "really high."
On the matter of the five year time-frame for Skyward Sword, Iwata jokes, "Can't you do it in three years next time?" Fujibayashi replies, "Sorry, I'll think of something that can happen in three years!"
Eiji Aonuma recently mentioned making the next Legend of Zelda game on 3DS an original, so perhaps Fujibayashi will be involved in that title, as well. But it seems some plans didn't even make it into a game as vast as Skyward Sword, as Aonuma adds, "There is a lot left that we didn't do this time."
We'll have to wait and see what's next on the horizon for Zelda, but I certainly hope whatever Nintendo attempts takes the series in a brave new direction. Either way, who's ready for more Zelda sooner rather than later?
