Neil Gaiman's comments are simply, flatly, totally inadmissible on this wiki. If the narrative doesn't state a connection between Cybus and Mondasian Cybermen — which Nightmare doesn't — then we can't assert it. For the moment, unfortunately, Cybus and Mondasian Cybermen survive as separate articles.

That's not to say that they won't/can't be refined in the light of Nightmare. But separate articles will indeed remain.
