“Winds of Winter” may not hit store shelves before the “Game of Thrones” season six premieres.

Winter is Coming quoted a GoT expert saying that George R.R. Martin’s much-awaited book may not be available before the debut of “Game of Thrones” upcoming season.

According to Winter is Coming, Jeff, a.k.a. BryndenBFish, wrote on his blog, Wars and Politics of Ice and Fire, before GoT season 5 began: “If you cornered me, put a gun to my head and told me to tell you how many completed manuscript pages are done for The Winds of Winter, I’d probably say that George is just north of 1000 manuscript pages with an expected completion date of late 2016 to early 2017.”

Following the recent HBO announcement that GoT season six will premiere in April 2016, Winter is Coming asked Jeff if his prediction change.

He explained that the average turn around time for a book to go from “manuscript submission” to “published and on the shelves” usually ranges from 4-6 months. Jeff said Random House published Martin’s “A Dance with Dragons” seven weeks after they received the final manuscript.

This means “Winds of Winter” may probably follow the same time line.

There have been several speculations that the fourth installment in the “A Song of Ice and Fire” series will be released earlier this year.  GoT season six is supposed to be based on “Winds of Winter.”

Martin recent cameo on Syfy channel’s “Z Nation,” in which he was seen signing autograph for the copies of a book titled “A Promise of Spring,” also made fans speculated that the book will hit store shelves in Spring 2016.

Meanwhile, the newly-released “Game of Thrones” season 6 poster created more buzz not only about Jon Snow being alive but it also teased that the sixth season of the hit medieval drama show will debut in April rather than in May as previously speculated.

The poster featured Snow, played by Kit Harington, and the word “April” was written beside him.

It was earlier reported that GoT season six has been delayed and will not premiere until May 1 after HBO announced that the new drama series, “Vinyl”, will premiere on February 2016.

Entertainment Weekly emphasized that the new poster showed HBO is embracing the speculations about Snow amid the fact that the network, the show’s producers, and Harington himself insisted that the character is really dead and will not reprise the role in season six.
