Posted this on another thread. Mean as well put it here.
In another forum someone commented that perhaps a proto faction of the Colonial Marines could come to play since this will be two expeditions that have gone missing, and Weyland-Yutani wants to know what occurred especially now that more than 2,000 colonists have vanished. They might send a team of these proto Colonial Marines to investigate.
Ridley's talk about 'the planet' there's three possible choices, LV-426, Origae-6, and finally Paradise.
I have a suspicion that David might actually be going to Paradise to eradicate the engineer race once and for all.
When the engineers arrive on Planet 4, they will find Walter and ask him who killed their people. Once he tells him that it was David, they will surely go after him, and if he's going to Paradise, the film could become a race against time since he could have created an army of Xeno and protomorphs to destroy the Paradisian population.
In the middle of this, if the Colonial Marines are involved, they will find themselves in the middle of this, and literally becomes what Scott talked about being 'war of the worlds'.
In the end, Lindelof was right. It was a diversion to seed the ideas of what's going to occur in this final film, though that's if its gets made after Covenant's lackluster performance.
Let's see what happens.
