My point was that there is no real such thing as "as intended" verses "as requested" especially since no one in the forums is really asking for Rob or Jamie to change the story.
I read somewhere that the original outline of this story was about 150k words, or maybe 150 pages. Regardless, I am absolutely certain that those 150k words or 150 pages were heavily revised. So if you're thinking "as intended" = original version, then that never happened. Then the author is also likely to rewrite entire sections of the storyline if they are an outline for events not covered in the main story yet. Even though Rob and Jamie did that 150k outline, I'm sure that outline wasn't just edited before the story started, but it has probably been revised a few times since the story started. Also, Most authors have at least one person review their work, even if it's only the wife or some other close relative, Then there is the editor and so on. Games are beta tested, story drafts are reviewed, movies are first shown to a target audience before a final cut is made...
So it's a given that almost all authors are influenced by others. What's important isn't sweating that an author might change their story because they were influence by someone else. What's important is trusting the author to allow only positive influences. If the author thinks something improves the story, why shouldn't the author add or modify it?
Now when I made my comment referenced by the op, I wasn't making any accusations. My brain just won't shut off and the possibility occurred to me. I trust Rob and Jamie though, if they did originally intend the Stanly invasion to be first unveiled in book 2 and moved it to book 1. Then they probably had a good storytelling reason, such as clearing up confusion.
edit - I spent about the last hour trying to find a nice reference by Orson Scott Card on his own revisions. He edited out something from Ender's Game so the second or third printing didn't have a certain reference. He thought after the fact that it detracted from the story so the new versions don't have the reference. However, a certain English teacher noticed the difference when he made it the focus of a class and his student's copy of Ender's Game didn't match his own. The teacher became very angry about the difference and attributed it to editors forcing Orson to abandon his creative license and degrade a book to make it more political correct--and wrote Orson a letter complaining about the fact. Orson's response I found to be very good. I was something along the lines of, "If I knew that that passage would become the focus of a classroom assignment, I would have edited it out even sooner." Of course, while I was looking for that reference Rob posted, but I'll go ahead and leave what I said, even though it ended up being out of order.
