So what caused all this is a production error over at BBC America Shop has sent the sets out early and some fans have been lucky enough to receive them. But be warned as some douchebag fans have found it to be extremely funny to spoil it for you so beware of the trolls and haters posting spoilers for The Name of The Doctor.
Production error in US means DW bluray shipped early. Let's hope no one spoils it for those who want to enjoy it together on Sat. Please RT— Edward Russell (@edwardrussell) May 12, 2013
