Read any good CCNP books lately?

I just passed my CCNA!! Whoo!
Now I want to take it further with a CCNP. I am looking for a few good books. Any recommendations?
Only concern is that the current exams are being replaced, beginning September. Is it too early to find good material for these new CCNP exams that Cisco is only now offering as beta exams? Is there really a big diff between the new and the old?
