George R.R. Martin Clearing his Schedule to Work on The Winds of Winter

For those of you who have complained about George R.R. Martin going to to many press junkets, or making to many TV appearances, or just attending to many cons around the world.  Well, you'll no longer be able to say that.  Martin took to his Live Journal to announce that he is clearing his schedule so he can complete The Winds of Winter.

In his Live Journal post he announces that he is cutting the World Fantasy Con from his 2015 appearances list.  And although it has not officially made its way onto his list yet, he also announced that he will not be attending San Diego Comic Con - poor SDDC, first Marvel announces they wont be attending and now GRRM.

It's the final sentence in Martin's post that is making everyone talk:

(Should I complete and deliver WINDS OF WINTER before these cons roll round, I reserve the right to change my mind).

So lets look at when these two cons are exactly.  San Diego Comic Con is in mid July, and the World Fantasy Con is in November.  So it is possible that George will finish and deliver Winds of Winter before either of these?  Well I don't think there's a chance we see the book finished before the end of the year, but I won't resist if Martin's surprises us all with an end of the year present.

So what do you make of all this?  Do you think there's any chance Martin finishes Winds of Winter before the World Fantasy Con?
