Yeah, I guess this could be good news for H/G fanfic fans...there's plenty of material from HBP for them to work on! I'm not sure how much detail we'll get in the H/G relationship in the final book. I mean, the book is probably going to be mostly about Harry "defeating" or "battling" Voldmort, so I can't see much of the story devoted to developing the H/G. I hope we do get to see more of Draco's story and how he ends up though.
