Pittbboi, it's painfully blinding, how much there is wrong in that post of yours. In my opinion, at least.
First off, let's point out that OoT and Wind Waker were directed by two different people, and the one that directed Wind Waker will be directing Twilight Princess. So more than likely, TP will take after the style of that game and Majora's Mask, insofar as story elements go.
Secondly, I don't understand your gripe with the small world thing. That applies to many Zelda games. Let's look at Ocarina of Time, where you save a reasonable number of people, but it's not a massive, FF-size world and ultimately you get no recognition for it. Or Majora's Mask, where you save a small world and at the end are placed back in your own world, alone again. Or Link's Awakening, where you basically save no one whatsoever.
Zelda isn't about huge, apocalyptic battles and saving millions of people. It's about the struggles of one person, Link, and the relationships he forms with the people he meets.
"Every character you meet either becomes a main bad guy or a main good guy, and there really isn’t much besides them."
This isn't even a matter of opinion, this is just plain false.
Darunia, Saria, Zelda, character like that are important, sure. But each only plays a certain role. And you have Impa, who becomes a sage but doesn't do a great deal beside that. And what about the hordes of characters (Kakariko Village, various Zora and Gorons, the kids in Kokori) that you may interact with, or do things for, or have them do things for you, but who don't become major characters? The carpenter's son. Ingo. The big Goron. Not to mention the nameless gerudos and marketplace people.
Ocarina wasn't a huge world, partially because of technological limitations. But it did have plenty of characters, of varying degrees of importance to the plot (or to Link as a character), and I think you're just overlooking that. You're conveniently remembering those certain characters who became sages, and not the large cast of other characters. You're looking at the important characters and saying only important characters exist, and that's simply not true.
The Windmill guy? Dampe the gravedigger? The Poe salesman? The Happy Mask Salesman? The running man? See, plenty.
