It's way too close imo for Dan to be writing this episode to be filmed now. They cast guest stars up to a month in advance, props might need to be made, I don't think Dan is such a 'short schedule' writer that he'd leave an entire episode left to film with only a week or two before it filmes. I believe every episode to be filmed is done and written already.
