Ripley, I mean Weaver, said that "Alien 3 and Resurrection and how Blomkamp’s sequel relates to them, stating that the new film wouldn’t “wipe out” those films but “run parallel” to them."
I think this will (at the very least) be interesting to see, as I still believe (AND HOPE!) that this film may just simply be a dream and the conclusion will be how the mystery egg gets on the Sulaco. But what do I know.
If they really wanted to give us an alternate Alien3, I would want to see the wooden monk planet more than any others, but that is just me. It was mentioned as one of the best sci-fi movies never made, after all.
