from the UK here, just watched it! (no lag of course)
a lot of new footage!!!
some new things worth noting:
we see what the creature looks like that goes into the arm (the snake looking thing)
we have confirmation of dead jockey bodies found in the cave that is examined by the crew.
there is new footage of what happens to some people who are infected or affected by what they discover, it looks dramatic.
there is some new footage of the hologram jockey, from what i could make out the running jockey in the hologram has its mask part of the suit on i think.
thats what i could remember, some new story hints were dropped (the company apparently through vickers seems to be cautious about the idea of bringing anything 'alien' back, this is interesting)
hope it comes onto iTunes soon!
