That was indeed a great article. I'll have to check out more of that site.
As for the John Hurt Doctor...I think at this point I'm in the "something else" camp. An unknown regeneration between 8 and 9 seems too obvious to me.
Plus it seems hypocritical for the Doctor that used the Moment to be seen as unworthy of the name while Ten who basically made sure it happened gets a pass on it.
Not to mention how anticlimactic it is to make the Hurt Doctor's horrible thing he did turn out to be something we already know about.
