Where are the "Harry Potter" eBooks?

J.K. Rowling is said to be publishing an adult novel later this year. Frankly, I'm quite curious to read it, but what I find even more interesting in this article is the fact that Ms. Rowling, who famously held onto all of the Harry Potter eBook rights, has yet to release them. Newsflash - Have you been to any yard sales lately? Who can't get hold of a $1 Harry Potter book and read it in print if they want to?
