The question is now can he finish it for the much-hoped-for spring 2010 publication date? And I think the answer to that is maybe not. He's written (or finalised, perhaps not quite the same thing) another 100 MS pages in a month, which is encouraging. If 1200 is still the target, than that is obviously even more encouraging: he could be finished in weeks. But the tone of the post suggests it might come in even longer than that, so factoring in the week he's spending on the TV show set, we might be looking at completion around New Year's for publication in the summer.

I think the February date was always extremely optimistic, although in that case it was GRRM's editor who suggested that might be possible.
