After spending a bunch of time in the beta, I think the biggest takeaway for me is how good Starfighter Assault is. They have absolutely nailed it. I quite liked the mode in the 2015 game, but there is so much more to do in it this time around, and everything from the controls to the density of the map just makes it feel a lot more like the movies. I also find it a lot easier to rack up kills compared to the previous game. Can't wait to see footage of the other space maps.
Regarding the other modes, I have enjoyed those too, but I think there are some obvious areas where they can improve it. For instance, the gunplay feels like it could be tweaked slightly, as well as the hero system.
Overall, I would say my experience with the beta has been pretty positive. Whilst I think the ground based gameplay needs a little tweaking, I am still having a bunch of fun, and will be excited to see how it evolves. As for Starfighter Assault, I would buy the game just for that.
