SkyNet excists!

[Liberator]

The new "Terminator - The Sarah Connor Chronicles" series has already changed the timeline prior to "Terminator 3".

Sarah dies of cancer before "T3" but in the TV series she and John have been brought forward to 2007 to form a new timeline and stop SkyNet.

I won't say anything else, except that Summer Glau of Firefly and Serenity is in it and she plays a similar type of personality.

Mmmmmmm, Summer Glau, naked in both the first episode of Firefly and Terminator-TSCC.
