The site said that's going to be a box set of 3 Ebooks by JKR. I think that Fantastic beast & where to find them, Quidditch through the ages, The tale of the beetle & the bard are going to be Ebooks, because they're sold in sets already. I know this isn't what people want to hear but it make sense. I checked JKR's Site & I quote "Updated May 2012 I have been enjoying sharing information about Harry’s world on Pottermore for free, and don’t have any firm plans to publish it in book form."
you know, after hearing that and going back to read the article, that does make sense. the article is about Ebooks, so it would make sense they were referring to those three books being released. i think what threw me off, and perhaps many others, is the fact that they said the word “new.”
i guess we won’t know for sure till this box set comes out!
