as long as the obvious issues are fixed the game will probably get around 83 in the press. the biggest mention will probably be no tactical combat, although i would agree with frogboy that tactical combat would be insane in this game.
my personal rating (assuming bugs get fixed): 75, with QoL improvements: 80, with balance and QoL and polish: 85, with new cool features (expansion content) like espionage, admirals, good mods, deeper diplomacy and so on: 90+
