National Treasure 2: The Book of Secrets. Although an official announcement hasn't been made, the fact that they have just purchased the following URLS is a good indication that the title is true. NationalTreasure2TheBookofSecrets.com and TheBookofSecretsNationalTreasure2.com Further evidence that this will more than likely be the title is that a while back the producers let out the bag that the sequel would have something to do with 18 pages that are missing from a book in John Wilke Booth's library, which has something to do with Abraham Lincoln.
