I wonder how much of that is due to the massive changes that YA as a genre has undergone over the past decade. In 1990 or 1995, an epic fantasy with a teenage protagonist would have made it over to the adult section, and teens would have found it there (Tad Williams's Memory, Sorrow, and Thorn, for example), but by now such a book is just as likely to get published as YA.
