The "Winds of Winter" release date may have been leaked online as the launch date for the "Song of Ice and Fire" book 6 has been allegedly set by George R.R Martin to be on October 2015.

Day Herald has reported that the "Winds of Winter" release date is going to coincide with the "A Knight of Seven Kingdoms" book launch this October 2015.

"George R.R Martin had a lengthy chat with his interviewers during the Game of Thrones press event. He revealed that the finishing touches on The Winds of Winter are presently being applied. These statements indicate that the book might release alongside 'A Knight of Seven Kingdoms' on October this year," wrote Day Herald.

Previously, the "Winds of Winter" release date was supposed to be on 2016 and that the "A Knight of Seven Kingdoms" would be the only book released on October 2015.

"His publisher confirmed there are no plans for the much-anticipated latest volume from his A Song of Ice and Fire series to appear in 2015. Instead, readers will have to comfort themselves with an illustrated edition of three previously anthologised novellas set in the world of Westeros," wrote The Guardian.

The Guardian then stated, "A Knight of the Seven Kingdoms takes place nearly a century before the bloody events of the A Song of Ice and Fire series, when the Iron Throne was still held by the Targaryens. Out in October, it is a compilation of the first three official prequel novellas to the series, The Hedge Knight, The Sworn Sword and The Mystery Knight, never before collected, and now set for release in a new illustrated edition."
