But it will sell the next book, retrokitten; the reference guide about each character.
I really don't know. I'm not sure if I will buy it or not (I thought I read or heard somewhere that the earliest it will come out is 2009 or 2010), but it has nothing to do with the DD gay thing. It has more to do with the fact that I don't really care what happens outside of the main story. I am a big fan of the series, but not so rabid that Harry Potter is my hobby, if that makes sense (I just flashed on an episode of Friends, "Gandolf is coming! We are sooo going to party!"). For me, everything was nicely wrapped up in DH.
I'm not going to lie, it was a bit of a shocking revelation, but once real life started later Saturday it was a non-issue.
