No definite date
But on Monday night the publishers dismissed those reports, again repeating the statement on their website saying:
"JK Rowling is happily writing Harry Potter and the Order of the Phoenix and we anticipate that we will be publishing later this year."
There's no definite release date - JK Rowling will simply announce when she's finished writing.
And Bloomsbury thinks that it's still likely to be this year, in 2002.
