As flagged on Reddit, Barristan Selmy actor Ian McElhinney made a claim during a panel in April at Epic Con in St. Petersburg, Russia, that will have book fans screaming: Supposedly, Martin has finished the last two books of the series, "The Winds of Winter" and "A Dream of Spring." He just hasn't published them yet.
"I don't know if you know more than me about this, but what I've been told is that George has already written books six and seven," McElhinney said. "And as far as he's concerned, there only are seven books. But he struck an agreement with David [Benioff] and Dan [Weiss], the showrunners of the series, that he would not publish the final two books until the series has completed. So all goes well, in another month or two, we might get books six and seven, and I'm intrigued to know how Barristan, for instance, ends up going through those final two books."

To me this sounds like wishful thinking of the highest order, but I hope against hope it is true, please. A story as good as A Song of Ice and Fire deserves a true ending.
