OK, I feel the need to make a contribution to this thread that's back on topic...
It would be interesting, but not vital, for Scott to introduce an Alien Queen into the next story.
Interesting, only because I think he would have some unique spin on the concept, not because I want to see the entire franchise linked up, storywise.
As for the egg-morphing vs Queen issue: it's been pointed out that a bit of elaboration of the life cycle can make an allowance for both. That suits me fine but if Scott wants to ignore the Queen idea entirely as though Cameron's Aliens story will never exist, that's OK with me too. That's because I've always seen the films in the franchise as being "alternate universe" contributions from each director anyway.
For the same reason, I don't care if "Covenant 2" (or whatever it's called) paves the way for the Alien 1979 movie to take place. The '79 film will always exist in my mind as its own unique and self-contained movie. It works beautifully that way (especially the special cut with the alien-nest scene restored), and the prequels already have a very different style than the one established in the Scott/O'Bannon/Shusett/Giger original. (I guess that's only to be expected given the decades of directing Scott did in the intervening years, and so too, his development as an artist,)
It's been said countless times before, but Alien 1979 is modelled on an unpretentious B-movie paradigm (and proudly so, might I add); Prometheus and Covenant are not. Collectively, to me, they will never feel like chapters in the same book. Not like Star Wars films, or Harry Potter films, Hunger Games, etc.
