heres a bit more-
"Using an augmented-reality book, kids can turn pages and watch themselves and the book animated on the screen. They’re creating educational and gaming content, including unique science and history stories.
Arguably these are little more than a big-screen series of tablet e-books, but with the addition of content by J.K. Rowling and others, this Sony effort shows a definite push towards younger gamers. The title, called Book of Spells, brings interactive fiction to the TV and allows you to turn the pages of a “real” spell book complete with moral poems at the end.
The book also interacts with the PlayStation Move wand to allow you to cast spells on the book in real life. The so-called books will require readers (players?) to interact with the book. With the Harry Potter title, Book of Spells, dragons leap out of the book and fly around the room with a bit of AR magic. It apparently even catches on fire requiring the user to put it out with their hands, leaving soot behind that needs to be wiped off."

according to cnet this will be $40 for the book and disc. however once you add in the cost of a ps3 and associated peripherals you need you're looking at at least $400. i don't know if this one book will work for all future 'games' or if you need to buy a new one for each subsequent title.
