The trailer is not entirely inaccurate, i would say it far more accurate than it its not, it says "Footage Captured in Engine", that is entirely believable, i was running the Evocati build at 4K Very High settings and it looked like that, gorgeous, stunning, visually its accurate. is suspect it was recoded in 4K, as for those camera angles, again yes the game has a cinematic camera system built in and you could replicate all of it, again i suspect this is actually how it was done.
The locations and ships, 90% of what you see is already in, the obvious ones are not, yet.
The sound, that's where it falls down, the audio fidelity in the game is awesome but in that video yes a lot of is enhanced for 'cinematic effect'
