Update:
No. There are only 10 books. And Amy and Dan found 17 clues in the series. And you're forgetting the fact that there are online clues through missions and cards.
It's going to be called "The Emporer's Code" and it's by Gordan Korman. Book 9 is by Margret Peterson Haddix, but I don't know the title yet. Check the 39 Clues Website for more updates.
There is not going to be a 12th 39 Clues book, but there is going to be a new 39 Clues series. The first book in the new series is called The Medusa Plot by Gordon Korman.
