Man, I'm glad it's the author pressing for the ending and not the publisher forcing a milk-the-cow-to-death scenario or forcing a rushed/last-minute ending.
I find it nice when an author has an ending planned/in mind (regardless of whether I like it or not; as long as it makes sense.) I've read a few series where there was no real reason for them to continue past a certain point because it wound up being a long, slow, painful roll downhill. (The main plot gets concluded but they, be it the author or publisher, need/want to milk the cow to death. They might beat the dead horse along with it.)
Let's end with a bang! (Not euphemistically ^_^; This is not that kind of series. Leave that for the doujinshi ^_~)
