That was a nice nod and is one of the only ties to T2 when we see the scar in a flashback scene near the beginning. I stayed till the end credits at my advance sneak and no there were not any scenes in or at the end of the credits. Of course Marvel kept the Nick Fury clip off of the Iron Man advance screeners so perhaps someone who saw it Thur can add if that is still true. McG has said the studio ordered him to make 30min of cuts to speed the action and pacing of the movie. He says there is plot and exposition in there he felt was relevant despite it slowing the pace down. I have to believe some acknowlegement of Kate's pregnancy is in some of those minutes. I also now see why the Moon Bloodgood nude scene is likely more important. She must have made love to Marcus thus strengthing her desire to help him once he is caught. I read that before and my thought was: Why at any point in the Future War does Skynet need human scientists?
