The music for TF4 has just been recorded, which means there must be a fairly complete rough cut of the film for the composer to pace out the music to (you can see the projection screen on one of the photos.

The car used for the character of Lockdown has also been shown off/reviewed to promote it.

Also being promoted is some sort of industrial Operations chair, which is apparently in the movie, but could be a spoiler, so don't check the link if you are trying to stay spoiler-free.
