Both Greg and Colin spoke today about the status of the AvP2 trailer. Greg said on IMDB that they’re still sorting out which trailer to use. Colin said here that they will see some new trailers tomorrow. Fox have been testing out different versions and there are two cuts which a lot of people like. They’re currently finishing the film off (and adding some new stuff to the movie) so that’s their priority.
Greg said that his estimate (of a week or so after Comic-Con) was a little optimistic but they’ll be letting everybody know what’s happening. I reckon it’ll be the middle of next week when we see it. Also, Colin revealed today that there will be two trailers. A green-band one and a red-band one. At the end of the green-band it’ll tell you the name of the website where you can watch the red-band version apparently.
