They really need to clarify if there will be post-launch support. It's the only thing preventing me from buying this game.
It's not built as a GAAS but they said updates are not off the table. If this game sells extremely well it would be baffling not to have more content especially since a lot of progression is based on cosmetic skins. Given how much shit EA has gotten over it's awful microtransactions in Battlefront it was probably a wise move to not bill this as a Microtrasaction fest.
Also the
official website has a lot of info about the maps and fighters. Example:
TIE/LN FIGHTER
Manufacturer: Sienar Fleet Systems
The standard starfighter of the Imperial Navy, the TIE (Twin Ion Engine) fighter is sturdy (despite a lack of deflector shields), faster, and more agile than its Rebel X-wing counterpart, and versatile enough to serve in multiple roles. Its speed, maneuverability, tiny silhouette, and good forward visibility give it an edge in a dogfight, while its armor and payload options make it useful against enemy capital ships as well.

Silhouette
Harder to see and hit from front or rear, easier to see and hit from the sides.
Cockpit visibility
Excellent forward visibility, including below the horizon line, but all other directions are mostly occluded. There are small viewports in the access hatch and the aft bulkhead, but the views are limited.
