This is an excellent point Bimie_James.
Many of the descriptions that we have read regarding footage released to small audiences such as CinemaCon wasn't in the movie.
That is why I'm still holding out hope that the Alien: Covenant sequel was filmed at the same time as Alien: Covenant.
Ridley Scott said this would go into production "within" 14 months, not beginning in 14 months. I don't see how that schedule works with the actor's availability, filming, etc...and ready for production "within" 14 months.
