UPDATE: Teaser online now above (and over at Yahoo!). Whaddya think?

Cinematical has been informed that the first teaser trailer for Terminator Salvation will most likely arrive tonight, around 9pm EST. Where? We do not know yet. Cinematical reader RossBond alerted us to the fact that Warner Bros. has sent out satellite coordinates for the worldwide trailer debut, and the time given for said coordinates is tonight between 9pm and 9:15pm EST. Additionally, there's also a 15-minute time slot tomorrow morning at 6am EST. However, if I were a betting man, I'd say the trailer will hit tonight. Fun stuff!

Here's the film's synopsis: In the highly anticipated new installment of The Terminator film franchise, set in post-apocalyptic 2018, Christian Bale stars as John Connor, the man fated to lead the human resistance against Skynet and its army of Terminators. But the future Connor was raised to believe in is altered in part by the appearance of Marcus Wright (Sam Worthington), a stranger whose last memory is of being on death row. Connor must decide whether Marcus has been sent from the future, or rescued from the past. As Skynet prepares its final onslaught, Connor and Marcus both embark on an odyssey that takes them into the heart of Skynet's operations, where they uncover the terrible secret behind the possible annihilation of mankind.

We're on it, and we'll let you know when we hear more ...
