I was waiting for this to come out, I had a feeling they would have TF's on the cover. It's the October 2007 issue. It's pretty pricey for a magazine ($13), but a nice read nonetheless. Nothing too groundbreaking as far as behind the scenes images go (a few green screen shots/model shots, etc.), but it goes into a fair amount of detail about the cg/practical fx process (similar to the articles Nelson posted in the weeks prior to release). If I have time I'll scan, otherwise I suggest you pick up a copy for the completist in you.
