No.
But if there were one, it would have to be some sort of spinoff. They'd never try to pass something like that as a main game in the franchise.
the next wiiu zelda is rumored to be open world so could be mmo?

Fire emblem.How would that work? Zelda games are all about figuring out puzzles and exploring dungeons. An online co-op adventure like Four Swords I could sort of see happening, but a full blown MMO? You'd probably have better chances with Pokemon. I can't really think of any other Nintendo franchises that would work as an MMO, really... except Kid Icarus Uprising maybe. An MMO of that could be pretty awesome.
The first NES Zelda was probably the most open in term of gameplay.the next wiiu zelda is rumored to be open world so could be mmo?
