Good read - the psychological approach to analyzing Sherlock's version of the story, with respect to his relationship with Mycroft, is quite interesting.
I am personally not satisfied with Sherlock's explanation of the fall. I've described why in another thread (basically, the version he begins to tell John implies a solution found by quick-thinking, whereas the version he tells Anderson is that everything was forseen and planned for ahead of time).
However, I feel fairly sure that we will not hear any more about this in the story. It seems like that's what TEH was all about - they offer some theories, and even the one told from the horse's mouth, and it's up to us to either accept or reject it. It was left ambiguous on purpose.
--------------------------------
I don't really watch television, except when I hear about an exceptional show that gets people thinking. The last such show I got enthralled with was Lost. I learned a lot about theorizing, and the reality of a scripted show (and how it's always much less clever than all the theories the fanatics come up with).
I feel like Sherlock follows a similar "mystery" approach to Lost. You get a massive "lego set" of ideas, which can be used to construct hundreds of theories. However, there is never a way to use every single piece to make a grand theory - there are just too many conflicting pieces. And most importantly, we the viewers are never told the actual answer.
But that's okay. While we might like to get a solid answer from the writers, it's way more fun connecting all the pieces in different ways and discussing the possibilies (hence why most of us come to places like this).
In fact, I always found this "mystery" approach to be a gift. If we are told "this is how it happened...", then we are done with it. But if all we're given is a rich set of tantalizing clues, we get to think, ponder, and theorize - we exercise our minds and imaginations.
And the grandest ideas now come from our own imaginations. By filling in the blanks ourselves, we create in our minds a much greater interpretation of the story than the writers could provide us with themselves.
At least, that's how I've always seen it.
