I hope they at least restored the extra scenes from the archives section for Alien (spider-walk, etc, etc). We already know that the Burke scene seems to have been restored for the 2nd movie, and there was quite a bit from the 3rd that was left off in 2003. As for Resurrection, there doesn't seem to be much left (unless they'll be showing us a little more human-alien action from the nest scene wink wink nudge nudge puke).
