The Zelda team is currently beavering away at the next game in the series, and it sounds like the title might introduce a different spin on the usual Zelda formula.
Shigeru Miyamoto has told IGN that the Zelda franchise requires "big new unique ideas," and added that the development team "is very focused on trying to find those ideas." He ruled out adopting a first-person perspective for the series, after IGN reminded him that Eiji Aonuma showed The Legend of Zelda: Twilight Princess played through Link's eyes at GDC 07. May we recommend a side-scrolling game interspersed with lengthy, high-quality cut-scenes? Oh, uh, never mind.
Anyway, while Shiggy's comments are rather vague, this does raise another issue: is the Zelda series growing stagnant? The initial outcry over Wind Waker suggests change is a delicate issue with the fans!
