So a few days ago, there was a post about Cybermen being in the Christmas special. Not the Cybus Cybermen, but the ones that were in 'Nightmare in Silver'. So that got me thinking... what will the Cybermen do?

A few days ago (again) there was a different post stating that all of the New Who doctors had some sort of thing happen that is related to their regeneration. For 9, it was the heart of the TARDIS (9 opened it and showed it to Rose, who also opened it and absorbed the time energy, which was then absorbed by 9 to save Rose, causing his Regen), for 10 it was radiation (he stated that Time-Lords can withstand immense amounts of radiation, which he absorbed more than he could withstand to save Wilf) but what will it be for 11? Back in 'Nightmare in Silver', when he was taken over by the Cyberplanner, he stated that he could regenerate right there and then and destroy all of the Cyberman tech inside him.

Could this be what takes 11? It very much seems so.
