Will the Prometheus storyline be a strong piece of the story in alien 5?

You have touched upon a few subjects and first i will take your last..... indeed i think they are going for something similar to what your last Paragraph was touching upon, it seems they are going for the Monsters, and Humans and why and only leave a few clues to the Engineers.

Your also correct as far as a movie trying to have to many themes, if the Source is true then it appears that Prometheus 2 was trying to cover too many things and it may have detoured from some of the important stuff.

Which Sadly Fox seems to think is the Xenomorph and Mankind and the next movie could be covering the Xenomorph a bit and then expand upon it in the sequels.

But a concern is that Alien Covenant will have Ripley connection and so it seems Fox may feel the Franchise is to be about Ripley and the Xenomorph....

Sorry but...

Ripley is just ONE HUMAN

The Xenomorph is maybe One Creation of Variant or a result of Experiments these Engineers had been involved in, there is more to the Engineers than just the Xenomorph.

The other aspect of the Franchise is the company the back ground between the company and what else they have dabbled with in which Androids play a big role and their is a lot of dispute and competition between Weyland and Yutani regarding Synthetics and what they did with David 8 was introduce a very interesting Character.   There is more to Weyland-Yutani than them wanting the Xenomorph as a Bio-Weapon.

Then we have the Marines... but its how do you expand on this without giving us a Marines vs Aliens as we seen this in Aliens and the constant Games.

So yes with the Back Ground that Prometheus has added it adds a lot of scope to the Franchise as a whole...  but it concerns me that FOX seem to still think the Franchise is all to do with the Xenomorph and Ripley....

As far as the Mystery then yes the more we see the Xenomorph the more it would be diluted and not as interesting or frightening anymore.  A Alien 5 and 6 would add two more Xeno movies (wont include Prometheus as it was not a Xeno Flick) so we would then have 5-6 Xeno movies, add to that the TWO AVP Flicks and then if Alien Covenant has 2 sequels that would show the Xeno more and more than thats potentially 10-11 Movies with Xenomorphs and at that point it would become STALE!

likewise with the Space Jockey again maybe it should have been kept a mystery and the origins of the Xenomorph.. but Fox are out to make Money and exploring those things can give them a means to make some $$$$$$

We also have to consider that Ridley Scott had no real input on how the Xenomorph evolved in the Franchise... Cameron had a input and we got Aliens... and then other movies after.

The one thing that has never been answered is WHO are the Space Jockeys and HOW are they connected to the Xenomorph and HOW/WHEN/WHY was the Xenomorph created.

Maybe these are best left unanswered..... but Fox will eventually answer these things, be it 5 years, 10 years or 20 in a complete Re-boot..... 

Ridley Scott lost control of maybe his vision for the Xenomorph... but he now has a chance to rubber stamp his mark on the Xenomorph Origins and Purpose and who the Space Jockeys are and their Agenda.

Ridley would rather work on those answers now... as Fox will answer them eventually and if this is when Ridley is to old or has passed on... then Fox could answer these things in a way that would make Ridley Scott and HR Giger Turn in their Graves.

Hi.  I am wondering whether the writers of these new movies (Prometheus and Covenant) have been inspired by a loose plot strand of Alien Resurrection who told of a breakaway faction of androids who began to manufacture themselves and started to rebel.  Perhaps David was this movement's progenitor.  Perhaps David (rumoured to be somehow responsible for the Alien's creation) brings about the some kind of war against mankind. Perhaps by the time of Resurrection's events he had been unsuccessful in his war, but had been successful in creating a new culture of independent androids.

welcome aboard...

And yes its possible, we have to look at the back ground for the Androids in the Franchise, Ash was a bit Twitchy as Bishop claimed, prior to Ash we have seen David models show some signs of dislike for Humans and in the back ground Weyland Website they had problems with previous David models prior to David 8

And while it may be a old cliche, yes indeed it could follow the plot like so many other Robot/Android/Machine movies which include Terminator, I-Robot and The Matrix.

The movie has ties to Prometheus Mythos and Paradise Lost Poem based on the Biblical tale of the Rebellion of Angels and Fall of Mankind.

Each of these has a theme where Creation turns against Creator and so yes its possible and likely we would see something in the next movies.

At very least as far as David 8

Hi.  I recall from the DVD extras from AVP 1 that Paul WS Anderson said that he would like to make Alien 5 with Sigourney Weaver (this of course being long before the advent of Prometheus), and that upon the success of AVP 1 Anderson had been commissioned to write the script for an Alien 5.  So presumably there is an unmade script for a post-resurrection movie sitting on a shelf somewhere.

At present, the Blomkamp post-Aliens project is being referred to (perhaps confusingly) as Alien 5, when perhaps it could be referred to as Aliens 2?  There are always possibilities, a movie set just after Alien featuring a story adapted from The Alien Isolation game is also an enticing prospect.
