My analysis of what we MIGHT be seeing in the video.
This is all very early in the game and is probably all within 3 hours of each other.
From this video, the 3 guys who are with Noctis appear to be his "squad" and not the actual final party much like what Tantalus(Blank, Marcus etc) was to Zidane. King Regis( most likely Noctis's father) is making arrangements with Emperor Aldercapt about something. At around 1:08, there appears to be an airship being televised by cameras which is probably Emperor Aldercapt making his way to the king .. maybe?
Noctis and his squad were most likely instructed not to leave the kingdom but of course the young and adventurous ALWAYS break the rules and leave anyways. While they're out doing what adventurous young people do, an astral Shard strikes near their kingdom. This is probably what happened at around 1:40 and is the reason why the sky is red and dusty.. maybe?
Also, that giant turtle looking thing at the beginning looks like an Adamantoise which is a popular enemy of the FF Series.
This could either be a small part of the world map or a more in depth Gran Pulse in this game. They brought the Cars back so I'm hoping Airships will be brought back aswell in a drivable form.
