It looks set that George R.R. Martin is readying himself for his final stage of reclusivity, in order to finish the sixth book in his epic Song of Ice and Fire saga before the 6th season of HBO's hit fantasy drama Game of Thrones airs.
In order to concentrate on finishing the eagerly anticipated The Winds of Winter, Martin once again decided against penning a script for Season 5. In an interview with Entertainment Weekly, Martin also revealed that he also turned down the chance of penning one for Season 4, and has canceled numerous convention appearances and interviews during the time:
[Finishing The Winds of Winter] has been important to me all along. I wish it was out now. Maybe I’m being overly optimistic about how quickly I can finish.
Martin will have to work pretty swiftly, seeing as season 5 of GoT has mined both A Feast For Crows and A Dance With Dragons, books four and five of ASOIAF, for impetus to continue being as incredible as it was from day one, and is looking to deviate majorly from its source material.
But the author has expressed regret at not striking at The Winds of Winter when finishing A Dance With Dragons:
I was red hot on the book and I put it aside for six months. I was so into it. I was pushing so hard that I was writing very well. I should have just gone on from there, because I was so into it and it was moving so fast then. But I didn’t because I had to switch gears into the editing phase and then the book tour. The iron does cool off, for me especially.
As it stands, The Winds of Winter still has no release date. so I guess "soon, maybe?" will have to suffice for now.
