From what I remember from the book it was pretty clear what Deckard is. But I agree, I liked the movie ending.
Is there more than one book? I've only read the first.

There are sequel books, but only the first was written by PKD. He died before the movie came out (although he saw parts of it and gave it his blessing). The sequels were written by a friend of his.
