July 21, 2007, the book stores of America will stay open late, keep staff happy with extra coffee and happily pay all the overtime necessary. The new Harry Potter book will be out and available for every kid and parent to peruse. It will be the final book of the extremely successful series.

The publisher of Harry Potter, Scholastic Corp. (NASDAQ:SCHL) is set to roll out 12 million copies for the initial print. That will be followed with an extensive marketing and advertising campaign, not that Harry Potter needs it, but hey, what the heck. The Potter series has already sold an astounding 325 million copies world-wide. It's not even out yet and it's already holds the number one ranking on Amazon.com. J.K. Rowling, the creator and author of Harry Potter may become the reigning champion of books sold.

Scholastic Corp. stands to have a couple of excellent growth quarters ahead. The massive campaign of the 7th book, will also spur add -on sales for the first 6 books along with the CD and DVD versions. Scholastic Corp is looking at strong earnings growth from the May 2007 Fiscal Year to the May 2008 Fiscal Year. Street estimates call for earnings to rise from $1.74 in 2007 to $2.59 in May 2008, nearly a 50% rise. The earnings progression may have a long tail as the Potter series may extend higher revenues well into 2009.

Daniel Radcliffe, the actor who plays the venerable Harry Potter should generate even more interest in the final movie than normal. Radcliffe is appearing in the London West End production of Equus, where he plays a disturbed young man and appears nude onstage for ten entire minutes.
