There has been some speculation about whether Dan Brown decided to drop 'The Solomon Key' as the title of his next book, due to an ambiguously worded story by USA Today writer Carol Memmott. There may be clues now though that TSK will indeed be the title of the upcoming book. The domains solomonkey.com and solomonkey.net were due to expire today, but on Friday both DNS records were updated, prolonging Dan Brown's ownership until the year 2016 (hopefully that's not an indication on when the book is to be expected...).

Add the above to that the fact that there have been no new trademark applications since Dan Brown lodged one for 'The Solomon Key', and it would appear that it remains the working title for the new book. Or at the very least, in the mix.
