In the meantime, lets examine the Cybermen.
The id is unconscious by definition:"It is the dark, inaccessible part of our personality, what little we know of it we have learned from our study of the dream-work and of the construction of neurotic symptoms, and most of that is of a negative character and can be described only as a contrast to the ego. We approach the id with analogies: we call it a chaos, a cauldron full of seething excitations...

Prologue: The Creation of the CybermenThe Age of Steel.
Centuries ago by our Earth time, a race of men on the far distant planet of Telos sought immortality. They perfected the art of cybernetics - the reproduction of machine functions in human beings. As bodies became old and diseases, they were replaced limb by limb, with plastic and steel.
So, will there be Cybermen? It does seem that there is at least a bit of a theme running.
But might series 6 turn out to be all about them?
