Don't believe everything you see on official Elite: Dangerous trailers. Horizons trailer isn't pure fantasy as original trailer but game doesn't look like that and some things won't be possible for awhile. Like dogfighting NPC ships on planetary surface. And of course Thargoids shown at the end of trailer won't be added for quite some time.
Elite: Dangerous patch 1.5 is for owners of base game, it will come online after they restart the servers (originally 16:00 GMT, delayed 18:00). Along with 2.0 update for those who purchased Horizons.
They also shared some info about multicrew that will supposedly be added in later stages of Horizons updates (late 2016). It will be slot based, max four slots per ship (based on ship seats). Will split everything you do as commander into four jobs. Based on wings, only wing members can man up the ship. Balancing sounds like a bitch because I see no reason why four people would man one ship when they can fly four different ships and be way more effective.
