I don't think Hicks will be a clone. I know that's been mentioned here a few times as a guess as to what might be, but it makes no sense. He's had an artist draw up hicks with the burn marks on his face, why would a clone have those same burn marks? NB is a very creative guy and I am very excited to see how he pulls this all off. He doesn't strike me as the kind of director that will just do away with A3 and A4 via some dream sequence thing. For me, I really want to see Hicks again, he was my favorite character along with Ripley in the series, I just hope he finds a very creative way of getting them together again. It is Sci Fi after all.
