Speaking in this week's issue of Doctor Who magazine, Davies wrote: "No, not the end, don’t be mad. Doctor Who will never end!
"There are pathways leading to potential futures – we’ve still got the mystery of that bright and blazing ending, 'Oh, hello,' yes indeed, hello Billie! And there’s Susan, of course."
He went on: "I wonder if we’ll ever find out who the Boss is. Or who the Boss are. (I’m still wondering who Gus is, from Mummy on the Orient Express. Maybe they’re the same!)
"But we don’t know what’s happening yet, and while everyone works that out, I’ll take a pause on this page ... Hopefully, we’ll have news soon, and certainly, The War Between the Land and the Sea is about to break out, so there are great things ahead. Until then."
