Rossicles at the TFW2005 boards, with an amazingly good eye, caught a glimpse of a new Sector 7 code in one of the new trailers.  Find and discuss it in this thread started by lonegamer8 in our forums, or you can scour the trailers again for it if you'd like an adventure and an excuse to watch  the trailers continuously (HINT: it's in a Bumblebee scene).
