We have seen that there will be changes to the map and that there will be a new area added. from the video alone we see that there is some sort of factory, a city, and a river. There also seems to be an addition of new islands and new ships. so things I would like to see are:
1. A larger more challenging fleet like the mod in SP 1, one thing that would be really cool would be for hostile aircraft carriers to spawn enemy planes.
2. This one is kinda far out but an airship aircraft carrier could be cool
3. better roads, it would be cool to see larger islands with fleshed out road systems, like paved highways and smaller roads going off of them, it would also be nice to see some smooth roads through areas with hills. this could really make driving cars and ground vehicles more fun, and give the opportunity to have races.
4. mission/ challenge maker it would give you the ability to make custom race check points and summon other craft
5. more boat traffic random boats would really add good atmosphere to the game and also be fun to blow up (this could be turned off in game rules for lower end devices)
6. better ground traffic, more convoys and traffic on the aforementioned roads.
7. just over all more POIs to explore, like caves and buildings
8. destructible buildings, I saw that there was a city and powerplant it would be cool if the buildings could be destroyed.
9. under water stuff, like shipwrecks corral reefs, and maybe a seamster that can be fought
10. ability to control what planes are spawned in random airtraffic
11. wave control, im not sure if the waves are actually real or just for looks but waves should be tied to wind and be bigger in deeper water and smaller in shallow water.
12. better wind

what do you think about this and what ideas do you have?
