The BBC is announcing Peter Capaldi's (the 12th Doctor) replacement on Sunday, July 16th!
Am I the only one who finds this video a bit ominous? They are announcing the new Doctor after the Men's Wimbledon final, which is not carried on BBC America. It seems that the 13th Doctor announcement will be shown on the BBC America Youtube Channel since the video post there says "See you on Sunday. Watch this space." - https://www.youtube.com/channel/UCdHkLMxTYwV66Sky1xXVrxQ.
