Another quote from Steven Moffat.
I kept referring to a mid-season finale. So we are going to make it two series – seven episodes at Easter building to an earth-shattering climax, a cliffhanger we could never normally do because it would be too long before it came back. An enormous game-changing cliffhanger that will change everything.
“The wrong expression would be to say we are splitting it in two. We are making it two separate series.”
So it appears we are getting 2 series next year??????
