I hope other Doctors have cameos as well. Would love to see Christopher Ecclestone. the most under-appreciated Doctors of the new millennium he deserves a spot in Who-story if for no other reason than regenerating the entire series. Not to take anything away from David Tenant (whom I adore) or Matt Smith, but without the ninth Doctor we would never have been treated to the wonderful performances of the more popular Tenth and Eleventh Doctors. It was good to see Rose, too. Great Trailer! Can’t wait to see the full show!
