Am I crazy for believing GRRM about TWOW (spoilers extended)

He mentions in his latest blog post that he will write the next dunk and egg story but AFTER THE WINDS OF WINTER. It sounds like he is working on it and it will be out soon (soon on the GRRM scale) but like everyone here I’m starting to believe it will never come out but the fact that he keeps saying it will (AND BEFORE THE NEXT D&E BOOK) makes me believe.
