harry potter

This post is in response to jerrycrew's post about Harry Potter (which was evil, it's like telling a 4 year old about Santa...), but it reminded me of a fleeting thought (of which I have many lately) I had when I finished the book...so I ask all you Harry Potheads out there.... Did anyone else feel like at the end of the book, that JK Rowling was setting herself up to write 4 more books instead of 1? I mean Harry has to find 4 of these pieces of Voldemort's soul (forgive me but I already forgot what they are called) and there is no way she'll let him find all 4 in one book, right?
