This is the first time in weeks when I may actually get to sit and watch this live, and hopefully join the commentary.
If for no other reason, I'm psyched to see the Cybermen again. Are these original CM or the parallel-universe version?
These are the original Telos cybermen. Apparently they have been the original ones since 2010 when they got their C symbols removed, it's just a coincidence they look the same.
I like to think however the original 80s cybermen bumped into a batch of Lumic Cybermen, concluded the Kumic cybs were better, and stole their technology.
