It’s very calm now, but it won’t stay like that. As soon as they’ll start filming, probably a few days before, that’s when things will happen here. There’ll be the first pictures from the set, reports from the fans who’ll be in Vancouver, tweets, theories, videos and all.It’ll last pretty much during the whole filming time.
David and Gillian should start giving a few interviews during this time, but the whole promo tour will start a few weeks before the series air, so I’m assuming around the end of January / beginning of February.
