There may not be another Skyward Sword-esque Zelda game
Though a lot of games in The Legend of Zelda series feature a different Link and Zelda, there have been a handful of instances where direct sequels to existing Zelda games were made. Majora's Mask was a direct sequel to Ocarina of Time, and Phantom Hourglass took place following the events of Wind Waker. In a recent interview, Skyward Sword Producer Eiji Aonuma explained that this may be the first and only time that we'll see that game's world and art.
According to Nintendo Everything, Aonuma talked to GameInformer and stated that it would be very difficult to follow up Skyward Sword. According to the producer, making a sequel or a prequel would be a huge undertaking for Nintendo.
"With Wind Waker, the graphics were suited to handheld gaming," said Aonuma. "Also, the game ended with Link embarking on a journey, so it left open the possibility of what comes after the game. With Skyward Sword, positioning it as the first Zelda game means everything else connects to it and comes after it. It becomes a little bit difficult to do something else within that world and certainly much more difficult to do something that comes before it."
I have to agree with Aonuma on this one. I can imagine how tough it would be for Nintendo to create a game that comes before Skyward Sword in the timeline. As for the art style, I think the difficulty would be in making a game that may use the same visuals as Skyward Sword but doesn't necessarily follow it in terms of its story. On the one hand, it's a shame that we may not see a game like Skyward Sword again. But on the other hand, I suppose it makes Link's latest quest that much more special.
