We’ve got a list of updates this afternoon for McG’s Terminator Salvation, which was the apparent smash at this past weekend’s WonderCon event in San Francisco. And while we await Rob Hunter’s report from the Con, we do have some new posters, images and a heads up on the next trailer for you.

First up is a gallery of new images. In addition to the new triple-frame poster above, the folks at Yahoo have posted another 8 brand new photos, including shots of McG calling the shots. Of course there are no images of Christian Bale having an outburst on set, just him looking totally badass as John Connor. Check out the images by clicking around in the gallery below.

The final order of news is that Yahoo Movies will be debuting the second full-length trailer for the film tonight at 7p EST. You can check out a preview over on YouTube with annoying Entertainment Tonight voiceover. The trailer will debut both online and on ET this evening. I would suggest the online version to avoid an over-zealous reaction from Mary Hart.

Terminator Salvation hits theaters on May 21, 2009.
