Did George R.R. Martin's 'The Winds of Winter' Release Date Leak? [Updated]

UPDATE: Here's an official response from Random House, Martin's U.S. publisher:

“As his publisher, we support George RR Martin as he works hard to finish The Winds of Winter. Any on-sale dates currently listed online for the novel are incorrect. Once we have a publication date for The Winds of Winter, the world will know.”

ORIGINAL STORY: George R.R. Martin's meticulousness has given way to a legendarily glacial pace in the realm of A Song of Ice and Fire. But the sixth book of the series that gave birth to HBO's Game of Thrones may publish in March 2017.

The info comes from an Amazon France listing, one that's still live as of this publication. Things that make us skeptical: no cover art, a highly improbably brief listing of 704 pages. If that length's true, we'd have to guess that Book 7, the finale A Dream of Spring, may be underway as well. Could we even dare for a fast back-to-back publish?

Entertainment Weekly reports that HarperCollins, Martin's U.K. publisher, said “nothing has been finalized regarding the publication or the date.” The magazine notes that Amazon Spain juked everyone with an incorrect release date a year ago, and that Martin has told fans time and time again that the official publication date would first appear on his blog when it materializes.
