Well, my impressions are thus:
This will give some utility to Multi-Crew, allowing a single ship to deliver and support a 3-person unit, instead of requiring each to bring their ship along and follow point to point.
Social hubs will be focal points of activity, something I've wanted to have more consistently for years. Hopefully these are more focused than just starports or Engineer bases, and are a more limited number of locations to concentrate activity.
I didn't see anything hinting at interactions inside of the ship yet, but that is a big hope. The Anaconda seemed a little small in the trailer, but that could have been perspective.
First-person combat doesn't quite hint at who will be on the other side; other players? Hopefully not just surface drones, NPC humanoid pirates and the like would be good, with some variety among them to encourage different combat styles and approaches.
No mention of them fixing the FDL's cockpit to be center-oriented. Biggest disappointment.
