I answered no, but it's a bit more complicated then that.
So will we ever get the game they hyped to us... no, just forget that pipe dream, that ship has sailed. CDPR management saw to that.
Will we ever get some of the stuff we were promised, my guess is yes, in paid expansions, where you'll need to fork over more money to get it.
So cut content is a thing in the industry, sure. But the amount of cut content and that the game no longer flows because they cut it all out and never really reworked it with their new new vision is the problem here. That and up to launch they were hyping certain features that either never made it in game, or are so watered down it's pathetic.
But modders will give us some of that back, I have a ton of faith in the modding community. The rest, we'll end up paying for it, just to get the expanion to allow the modders to perfect it. Think Fallout 4 style expansions.
