Compare the headline of the Mirror's story: 7TH HARRY IN 2006, VOWS JK -- to the actual contents:

She wrote: "2006 will be the year when I write the final book in the Harry Potter series.

"I contemplate the task with mingled feelings of excitement and dread because I can't wait to get started, to tell the final part of the story and, at last, to answer all the questions (will I ever answer all of the questions? Let's aim for most of the questions)."

She plans to start writing the seventh book in January, hinting it may be called Harry Potter and the Pyramids of Furmat.

Whatever the case, she's only *writing* the book next year, not necessarily finishing it. Big difference, of course...
