Speaking to IGN, Shigeru Miyamoto has fleshed out a brief announcement in the Nintendo press conference last night that there are new Zelda games in the works.
"The Zelda team in particular always works on Zelda titles," he said, shockingly. "The core members of the Zelda team have for a very long time now been focused on Zelda games, and continue to focus on Zelda games, so they are hard at work and working away.
"And then, of course, we have the DS Zelda team as well, so even there we're having some switching of people in and out where the DS team is mixing in with the Wii team and working on the Wii version."
