To be fair the Guardian story only references Terminator in the header. The text body is written by Lord Martin Rees and is a short but clear description of X-risk without any sci-fi references. It also focuses more on other X-risks, perhaps a difference in opinion amongst the founders?
Tallinn and Price are very concerned with AI-related Xrisk. Martin Rees currently considers biological risks his no.1 concern (which is not to say he's unconcerned by AI); he's famously offered bets on a major (~1 million death) bio-related catastrophe occuring in the coming years. http://online.wsj.com/article/SB124121965740478983.html
As of an hour ago, I had not yet heard of the Centre for the Study of Existential Risk.
Luke announced it to Less Wrong, as The University of Cambridge announced it to the world, back in April:
CSER is scheduled to launch next year.
Here is a small selection of CSER press coverage from the last two days:
