If there are no xenos in Prometheus, I'm going to feel the same way I felt when there was no Newt or Hicks in Alien3.
Just watched the full res on my iPad....awesome...a couple of new shots. We've had these same images for a while so I'm a bit disappointed they didn't release something different, but oh we'll.
Didn't you say of Rothman's response to the trailer leak "Why is it unfair?"
Well, here's your answer. Without the leak your first exposure to all these images would have been HD and you'd have been all the more stoked by the revelations and scale. The leak undermined the impact somewhat, (although not too much in my opinion), and it led to a lot of flawed speculation because the low res picture maybe hinted at things that weren't there.
