It all depends on how square handles this post release. If nothing gets fixed, modders will fix it and it will get rightfully review bombed on steam. It will probably still sell a decent amount though. As it is now, the EGS/pirated version runs near perfect with mods applied (ultrawide fix 2.0, dynamic resolution disabled, forced DX11, etc.). Who knows if we'll get any fixes from square by the time it hits steam.
Square really just sent this one out to die. They collected the EGS payout, dropped the game on the floor and ran. It legit wouldn't surprise me if square had one of the facility janitors handle the port on their days off.
