As someone who love the game and have 188 hours right now put into it, I don't expect the game do really change with patches or DLC's. There's many parts I wish were better, at least on the level that CDPR said just months before release. Because yeah I did have expectations, again based on what they said just months before release. And not based on the old 2018 demo because they did put a disclaimer all over it that everything is subject to change.
But I don't think the game can be "fixed", like add in actual decisions in the story and not how it is just right now and comparable to say a Tomb Raider game or Assassin's Creed games - linear story, which Cyberpunk 2077 absolutely have. It's gonna take too many work hours and resources. CDPR are more likely to abandon the game and focus on the multiplayer version as well as any other game they have in development. However fixing bugs and glitches they will certainly do.
That said, I will continue to play it until I finish the main story and all side stories. At that point I'll stop and most likely will never play it again. DLC's won't get me back. Some extra side quest in a DLC will not make me care. And any expansion can't really expand upon the main game in any meaningful way - something to do at the end game because there is no end game. The story stops and that is set in stone no matter our choices throughout the game.
