My view is it might be true, it might not. Fact is though, the BBC does leak bits and pieces to the tabloids, and it wouldn't come as a surprise at all if in the next few days, prior to filming beginning, there's a press release about the outfit, the adversary and the new TARDIS.
I'm not claiming the article to be correct, but I'm not going to start bleating "FAIL FAIL FAIL" either.
