You've obviously misunderstood what i wrote. I never said some series aren't planned as a trilogy, i said the story is not planned out from beginning to end. They may start with the basic premise of the story, but the detail and real content is created as the story is written, the twists and turns and surprises are added as the story is fleshed out. For instance, do you think JK Rowling knew what was going to happen in Harry Potter 7 when she was writing number 1? Of course not, the most she would have known was that Harry would fight Voldemort, the rest of the story would have taken shape as she wrote it.
E@G seems to think that the detail in these stories is, or should be, already planned out in detail, in advance. Which is obviously not the case.
I've forgotten more about writing than you'll ever know. The fact you think these things are planned from beginning to end in detail, just shows you've barely read a book in your life, never mind a trilogy or series of books. You are making yourself look ignorant, for your own sake, stop.

That's just totally wrong, like the rest of your examples,
here's a draft the Wachowski brothers did in October 2001, two years after The Matrix was released. I'd go through the rest and prove you wrong with those too, but i have neither the time nor inclination, besides, i think this one alone is enough to demonstrate how little you really know.
