I am just throwing this out there for all of you to shoot down, but what if the name of the doctor was
revealed, and it was Walter Simeon? We know the human Simeon died, but that the GI that had been a reflection of him then took his form and persisted. We also know that somewhere (was it the Cartmel plan?) the Doctor is said to have originated as a 19th century human scientist that developed time travel and made his way to Gallifrey to become The Other. Could Simeon/GI be that guy? Or do you think it just a coincidence that Richard Grant played the Shalka Doctor?
I sorta think Hurt is a reconstruction of the part intended for Eccleston, and the real revelation is about the relation between the GI and the Doctor.
