Saw new Prometheus figures at TRU yesterday courtesy of NECA. They had the "flight suit" alien dude and un-suited alien dude. Those appeared to be the only two. These looked pretty cool, but didn't seem to have a lot of play features. Which I guess makes sense as these are probably not aimed at kids.
Not sure about the scale, 10" maybe? I am horrible at guesstimating dimensions, so I could be way off there.
