Who is Ecclestone? For crying out loud, at least get the name right.
Now aside from that, you really thought it would be a pre-Hartnell doctor? Really? Just the clothes alone pointed to a "doctor" between 8 and 9. It was obvious from the moment Hurt appeared on screen. You even touch on it in your original post "He's the one who broke the promise" Not, He's the one before he made the promise.
Now, there may be a filmed regeneration, a CGI regeneration, an implied regeneration, a "reflection" regeneration like in the Night of the Doctor. Or no regeneration at all. Given what the Moff has pulled off so far, I'm not discounting anything.
