In summary:
•Prometheus 2 will not focus primarily on Shaw and David on board the Juggernaut they escaped in. This time frame is said to be glazed over, since Shaw will be incapacitated for most of the trip anyways.
•There will be 3 main plot lines, Shaw and David's mission to Paradise is only one of these three.
•The Engineers are NOT our creators, but servants to a higher being, much like David is to Humanity.
•Prometheus 2 WILL link LV-223 and LV-426, it will provide some answers to Alien, but it won't be an 'Alien' movie.
•Prometheus 2 will feature 2 monsters - both having connections to the Xenomorph, but are not Xenomorphs themselves.
•There will be a loose connection between the Engineers and the Prometheus myth, involving "fire", however we believe this is in a metaphorical sense.
•Project Prometheus was not the first mission to LV-223.
•The Black Goo will return, but not as a weapon, but as a means to create life - the forbidden fruit, if you will.
•Evolution will NOT be the focus, but instead the hierarchy of creation and ancient Gods.
•David wishes to play God himself.
•Ideas from the original Star Beast will be incorporated.
•Prometheus 2 is said to have a very Matrix and Blade Runner feel to it, regarding the agenda of the Creators and the Engineers.
•Prometheus 2 will have a much larger cast, not a smaller one.
•Ideas which didn't make it into Prometheus will make their way into Prometheus 2.
Here is Big Dave's full recollection:
As i mentioned on THANATOS_CONTAGION post, i had a conversation with someone i know, who said they had spoken to someone who has some idea of what Prometheus 2 is about...
I can only take these as pure Speculation but this person did 6 months ago or near enough, say that they also seen some concept work for the movie....
Anyway here are the things this person was hinting at, and by no means can we take these as FACT in any shape or form, but may be interesting to discus these points if they are some area the movie could go....
1) The Movie will have 3 Plot Elements, and Shaw and Davids mission to find the Engineers Homeworld is just one of those.
2) The Engineers are not God or our creators, but a servant race for some other purpose. So merely as David is to Mankind.
3) Shaw and David will not be getting the Answers they want, what they find is truely Horrifying Agenda. Revelations that separate even further the original answers Shaw thought they would find when they got to LV 223 in the first movie.
4) The Movie will give us more of a link between LV 223 and LV 426, and it will provide some answers to the Alien fans but it wont be a Alien based movie.
I guess the fan boys fix will come from Alien 5
5) There will be two Monsters One new, both will have loose connection to the Xeno but they will be different.
6) There will be some connection between Engineers and Prometheus Myth but this is loosely.... related to the Fire.
7) The movie will not be based largely on Shaw and David shenanigans aboard the Juggernaut but there will be some screen time devoted to Shaw and David during the trip but not actually interacting as such on the ship. As Shaw will be incapacitated for the most part.
8) Prometheus was not the FIRST company mission to the Zeta 2 system.
9) The Black Goo is not quite how its shown in the movie, they are going the route that it is the Origin of Life, the Blood of Life and all creation. And kind of like from the Tree of Life and Forbidden Fruit.
Pretty much i guess how the Comic Books Fire and Stone was going.
10) If we are expecting a evolution and more depth to the Ancient Aliens connection, this wont be the case but we could see a slight connection as far as some Ancient God connections. As far as Hierarchy and Order of creation.
They kinda said like how David is part of that Hierarchy.
11) David wishes to play God himself and continue the order of Hierarchy.
12) They are following some ideas from Star Beast as far as connection between the said Hierarchy of creation seen in the movies. This could be regards to Engineer connection to their purpose. And connection to Sacrifices.
13) The movie plot has kind of a Matrix and Blade Runner theme to the Agenda of the creators. And Engineers.
14) The movie will have larger cast than Prometheus and so not a small Cast as we may have thought or been led to i.e Shaw and David on a ship to find a God.
15) The comic books followed LV 223 and 426 and while the events show what could happen, the comics are to be considered a alternative. But underlying themes could be explored.
17) There could be some ideas and things that they never got round to include from Prometheus that could be done in Prometheus 2
He goes on to add some very interesting notes as well, regarding Prometheus 2 concept artwork which his friend had apparently seen early on:
They said kind of like how AVPR shows what happens to a Face Hugged Predator to create Pred-Alien.... this event is not canon to Alien Franchise, but it is accurate as far as a what if Predators was part of the cannon and got impregnated with Xeno Embryo
The above is kina what was said, it may changed bit word for word as i trying to remember every detail...
