Lack of blog post from GRRM and potential Winds of Winter update?

Ok, so this will be a really nonsensical copium, but this came to my mind today: What if a lack of blog posts from George these days is due to him meeting with his publishers for Winds of Winter? And this is not about Winds of Winter actually being finished, but about him and the publishers working up with releasing whatever George has written so far into a book, similar to what happened regarding Feast and the Dance. And yes, George says that he wants to finish the series in seven novels, but maybe came to the conclusion that that would be really difficult. Or maybe his publishers have pestered him enough to release something to continue the story. And again, I am simply theorizing.
