The UK's Independent has a small report saying that industry speculation about an Autumn 2006 release for The Solomon Key looks to be off-base:

Meanwhile, Transworld plays down speculation that Dan Brown's new book, The Solomon Key, will appear next autumn. To think that the health and wealth of so much of the book trade is conditioned by the actions of a reclusive ex-teacher.

So when should we expect it? A Xmas 2006 release perhaps, or will the release be pushed right back into 2007?
