This post should probably be in both the PROMETHEUS and ALIEN 5 boards.http://masterherald.com/prometheus-2-to-have-a-connected-plotline-with-alien-5/12190/
Like most of the articles I am reading regarding the development of Alien 5, this one seems to have been poorly researched. There are several articles claiming A5 takes place b/w Alien and Aliens, others b/w Aliens and A3, and others claiming it is ignoring the 3rd and 4th films.
All of this stuff seems only further complicated by Blomkamp's vagueries.
This time we are cast into doubt by Blomkamp having said that his Alien's connections to Prometheus, he felt, should be kept in his hand of cards...
So here we are with this article claiming it does indeed have a clear connection to P2.
But it also asserts that Prometheus 2 does not yet have a script.
We all know Ridley Scott has confirmed multiple times that the script was redrafted several times before he declared it "ready to go."
