They are on major updates, but they did say on one of their latter interviews that minor updates might still happen.
"While the team is now finally writing off major updates to
Cyberpunk 2077, Amatangelo isn't ruling out smaller updates entirely, saying, "
It's possible that there's some other little thing that comes in here or there, just because, as you're kind of messing around with stuff, sometimes you discover something that is not a high risk. Or it's easy to integrate."
Which I hope is true,
and here is a link to the interview.
I also do have to say, they did a good job fixing what should have been when first released, and it's one of the few games I will keep playing for a while. I do hope the next sequel continues on with the same style of game play.
