The New York Times is reporting that Dan Brown's publisher plans to release a paperback version of the best-selling novel a week before the release of the movie version (mid-May). Sales in the U.S. have been so strong that there has been no need to offer the cheaper version, as the more profitable hardcover version has remained high in the charts for the past three years. However, Brown's publisher is expecting a big response to the cheaper paperback - in conjunction with the movie release - and is printing five million copies (to go with the other 40 million copies or so currently in print!).
