The Inheritance ... cycle?

I enjoyed Eragon. Paolini's world was full and fun with lots of action and meaningful characters. Eldest was not as good. The story slowed and had too much drama. Only in the end did I feel any kinship with the first novel. Now Paolini decides to break his trilogy into four books because he felt some morality portion needed more exposition. This does not bode well for my taste. Brisingr is set for a 20 September 2008 release in the states. If you go onto the amazon site you can find a statement by the author defending his decision. I will read Brisingr and hope I am pleasantly surprised.
