We're not going to know until the final release, I suspect.
I'd love to see a version of the film with:
- The Millburn/worms scene
- The alternate Shaw and Holloway love scene, though I'm not sure how it'll play
- Janek and Vickers after Holloway's death
- The longer take of the Weyland/Vickers scene
- Weyland's speech back in the Engineer scene, but nothing with the Engineer talking
- The longer fight between Shaw and the Engineer
- The dialogue between David and Shaw before her return to the juggernaut restored
