^I'm sure they'll be discussing the Ramsay/"Arya" betrothal this year (it comes up at the end of A Storm of Swords
, after all), but the actual wedding at Winterfell and subsequent events seems destined for season five. With Michael McElhatton saying he's not in this season much, they probably aren't pushing beyond the third Reek chapter, if even that far.
What's weird to me about Martin's comments is not so much the denial (he's good at denial, as an array of blown self-imposed deadlines suggests) as the fact that the show's writers haven't snapped him out of it yet. Surely they've told him by now, when they're probably about halfway through writing season five, what their actual gameplan is? They usually meet with him this time of year or earlier to outline what they're doing with the season.
