Summary on CNN Rowling: So you want to know what happens next?
Complete transcript on The Leaky Cauldron.
I'm glad Jo filled us in! This info, plus the Epilogue, should be enough to keep other authors from trying to "fill in the gaps" -- and it's so much better than Sir Arther Conan Doyle's Reichenbach Falls solution for dealing with Sherlock Holmes. I don't know if this will satisfy readers' desire for more Harry Potter stories, but it's good info.
