They still use three books partly due to the large amount of content (all three would equal a very thick book), but I also think its something of a sacred cow. D&D was originally based on the premise that the DM was supposed to have secret knowledge of the game. Keeping it in a separate book helped, and I think the format was kept as a matter of course. I like the set up, personally. If I'm playing, I only need a couple of books. If I'm the DM, separate books is the next best thing to a laptop and pdfs.
