Terminator Trailer: Get It While You Can

Here's the teaser trailer for Terminator: Salvation. It's the perfect teaser trailer!!!

But here's the problem I'm having: they just started filming this movie and they already have so much to show. WHERE IS MY STAR TREK TRAILER!!!!????? OMG, they've been done filming that forever!!! It must suck so badly if they have nothing to show yet!
