One of my friends is down at Amundsen-Scott, currently for his second overwinter. He works on the BICEP2 project. When I saw this I was worried it might be him. I was able to reach him over the internet and he let me know he was doing well. They are understandably keeping quiet about what is going on, so I can't offer any details, but it sounds like the patient is doing OK for now. That's all I know.
