While part of me doesn't like to wait for a new Zelda game, I've said for years now that I think the frequency of new releases is getting out of hand.
1986-2000 (little over 15 years):
The Legend of Zelda
The Adventure of Link
A Link to the Past
Link's Awakening (also DX revamp)
Ocarina of Time
Majora's Mask
*Does not include spin-offs like BS Zelda no Densetsu, BS Zelda no Densetsu: MAP2, BS Zelda no Densetsu: Inishie no Sekiban, Link: The Faces of Evil, Zelda: The Wand of Gamelon, Zelda's Adventure, or the LCD games (Game Watch, Game & Watch, Barcode Battler)
2001-2011 (roughly 10.5 years):
Oracle of Seasons
Oracle of Ages
The Wind Waker
Four Swords (with A Link to the Past revamp, also on DSiWare)
Four Swords Adventures
The Minish Cap
Twilight Princess
Phantom Hourglass
Spirit Tracks
Ocarina of Time 3D
Skyward Sword
*Does not include spin-offs like Freshly-Picked Tingle's Rosy Rupeeland, Tingle's Balloon Fight, Irozuki Tincle no Koi no Balloon Trip, Link's Crossbow Training, or Master Quest.
In roughly the past 10 years, we've had roughly double the amount of Zelda games released as in the previous 15 years before that. I do want things shaken up in terms of who's developing the next Zelda games for WiiU/3DS, but I also don't want them to rush things. I'm not sure if the OP was getting at creating two dedicates teams with two heads to get more Zelda's out, and possibly on a more fixed schedule, but I think that's a bad idea.
