I think part of the problem (Which is unfortunately very Common) was that success of the Series itself led to him adding in more and more, without anyone really wanting to tell him enough is enough.
As long as people Like us kept on buying, there was no real incentive to shorten up and finish.
I've read the series from Book one to ten at least half a dozen tmes, and you can really see how he seemed to have lost focus on the ending sometime around book 4 or 5. I actually stopped reading around Book ten, deciding to only go back when the last book in the series comes out.
