"Macmillan, one of the nation's largest publishers, said it will issue books it expects to be best sellers in an enhanced electronic-book format, starting in the first quarter of 2010. The special editions, which will include author interviews and other material, such as reading guides, will carry a list price slightly higher than the hardcover edition. (Hardcover books typically list for at least $25, while e-book versions of best sellers can go for as little as $9.99.) The new e-books will go on sale on the same day as the hardcover. After 90 days, the special edition will be replaced by a standard e-book. ... "Our goal is to give the consumer what they want, when they want it, at a fair price," said John Sargent, chief executive of Macmillan, whose imprints include St. Martin's Press; Farrar, Straus & Giroux; Tor and Henry Holt & Co. Mr. Sargent said the company, working with its authors, will adjust the number of special editions it publishes based on market response." - from WSJ
