To the OP, Gemini-Phoenix, it seems you didn't know that Nintendo/Miyamoto said that Twilight Princess was the last Zelda game of its kind.
The next main console Zelda game, which has been in development for Wii for several years, will be very different from Ocarina of Time and Twilight Princess. Nintendo is looking to come up with new ideas, a new direction for the next Zelda, and, to build it from the ground up for Wii, unlike Twilight Princess, a Zelda game designed for GameCube and only ported to Wii with quickly tacked-on Wii Remote controls.
I expect some annoucement on the next Zelda game at this year's E3. Although Miyamoto said last year that he was unsure if he would be able to show anything of it at E3 2009, so we'll just have to wait.... I also don't expect it to be released until fall 2010.
One thing can be counted on, the gameplay/control system will be totally new, and will take advantage of MotionPlus. As soon as Nintendo showed the sword slashing gameplay in Wii Sports Resort, it became completely obvious that the next Zelda would take advantage of this. http://www.youtube.com/watch?v=b1emrtvihg8
