xD She probably said that because if she said an absolute NO, she might get a lot of angry fans on her butt. Her answer was vague, so I highly doubt she will be writing anything more. A good author knows when her audience has grown up, and when she needs to stop. (For example, they are dragging out the movie franchise waaay too long. They have the full final movie done, the only reason they split it into two parts is to have the hype drag on longer, because once its over, thats it for Harry Potter.) J.K doesnt need to write anymore anyway. They say authors will usually have that ONE phenominal idea, and they will write it, get famouse, become rich, but then never have another idea like that again. I think this is whats happened to J.K. She is richer than the Queen of England. Harry Potter was an immense success. If she were to write a new different series, I would find it strange to read because to me, she is Harry Potter, she invested so much of herself into those books that I don't know if she could replicate that again in another series.
