Harry Potter release date pushed back to July 17 2009. 

Ok so you've probably heard the news but if not just follow the link above for more information. 

At  first I was absolutely distraught, I mean screaming Nooooooooooooooooooooooooooooooo!! at my computer and crying and stuff and now I still am kind of really annoyed. But there's nothing we can do but wait for another year. It means a two year gap between Ootp and HBP. But if HBP had been released this year then there would be a two year gap between that and the first Deathly Hallows. 

The facts are WB are just after more money (well that's what I and most of the fandom reckon anyways)
