If this movie doesn't acknowledge A3/A:R, and is essentially an "alternate Alien 3", then Hicks/Newt never died and it makes perfect sense for them to appear as alive. As an alternate continuity, it isn't overwriting A3/A:R at all. Its just a separate continuity, so those of you who don't like it can disregard it just as I disregard A:R. Prometheus, and AvP. But there's nothing wrong with seeing another way the story could've turned out, which is a movie I DO want to see. A3 IS a great film, and has grown on me over the years, but was still a mess and not what even the people working on it wanted it to really be. A:R on the other hand, was complete corny garbage and thank God its not continuing with Ripley 8.
