Here are a few reports about an online chat she had today with schoolkids. Pity I can't find a transcript, because each report is different and she apparently revealed quite a lot.

Rowling Hints At Potter Future
Harry Potter author J.K. Rowling told participants in a World Book Day Web chat held today that the wizarding world "is really at war again" in book six, which she is currently writing. "[As a result, Harry] has to master his own feelings to make himself useful," Rowling wrote. "If personally I was Harry Potter, I would hide because I know what is coming."
Rowling has long declared that book seven would bring the Potter saga to an end. However, responding to one of the 16,000 questions she was asked, Rowling said she could not rule out penning a story about Harry's life after he completes school. "Probably not, but I'll never say never because every time I do I immediately break the vow!" she wrote.

J.K. Rowling Hints at More 'Harry Potter'
Harry Potter may be set to grow up. Writer J.K. Rowling hinted Thursday that she may not stop at seven books about the adventures of the young wizard and may write a further installment featuring the adult Harry.
In a live Web chat to mark World Book Day, Rowling - who has always insisted she'll write only seven Potter books - was asked by a fan if she intended to write books about Harry after he leaves Hogwarts, the academy for wizards.
"Probably not. But I'll never say never because every time I do I immediately break the vow," she replied.
Rowling, whose wealth was recently estimated at $1 billion, is writing the sixth Potter book. The most recent installment is "Harry Potter and the Order of the Phoenix."
"I can't say when it will be released because that's down to my publishers," she said. "But it's going really well. I am loving writing it."
She promised the latest book would include more romance for the boy wizard, but hinted he would also face a terrible ordeal. She added that she planned to try a "completely different genre" of writing when she has finished the seventh book, but did not specify.
More than 16,000 Potter fans submitted questions during the hour-long discussion.

JK Rowling would love to fly like Harry Potter
By Paul Majendie
JK Rowling would love to follow in the footsteps of the world's most famous boy wizard and fly on a broomstick like Harry Potter.
And, if she had a chance, Potter's creator would take Harry out to a meal and apologise to the hero of Hogwarts School of Witchcraft and Wizardry for all the ordeals he faced.
Pottermania struck again on Thursday when Rowling was bombarded in a live Web chat with 16,000 questions from avid readers of her wizard sagas.
Obsessive children with an encyclopaedic knowledge of the Potter books tried to tease out of Rowling her plot lines for Book Six which she is currently writing.
No joy.
When asked if the wicked Voldemort would die, she replied in the World Book Day Web chat: "Now do you really think I would answer that?"
But she was more open when asked about the magical powers she would like to possess, taking a gentle dig at the global cacophony that greets the publication of every Potter book.
"I would like to fly. And sometimes turn off other people's voices," she said.
The release in June last year of the fifth book was billed as the world's biggest book launch.
Asked what would happen if fiction became fact, Rowling said: "I think I'd most like to spend a day with Harry. I'd take him out for a meal and apologise for everything I put him through."
Then she teasingly warned that even tougher times faced Potter: "In Book Six, the wizarding world is really at war again and he has to master his own feelings to make himself useful."
"If personally I was Harry Potter, I would hide because I know what is coming," she said.
For all those children who know every twist and turn of the Potter plots, she had a word of warning -- when she finishes the saga with Book Seven, she will settle down and revise them all.
But she promised there would be no prequels. "You won't need them. By the time I've finished you'll have all the back story you need."
