Okay. So all the Doctors got a look in, except Eight. I didn't see him or hear him ANYWHERE. This cannot be an oversight (ETA: apparently it actually was); I'm convinced, utterly, that this means something. Especially given that all the on-set shots of John Hurt seem to show him dressed in Eight's waistcoat with Nine's leather jacket.
A couple of smaller observations.
When did he change the TARDIS control room again? I just rewatched the first season of his run and it's definitely different, more whimsical and steampunk, than it is now.
Another: he's dressed differently. Long coat, waistcoat and watch chain. Are there Reasons?
Oh, and the stock footage gave me LIFE.
That is all for now :D
