Nothing. The ship has sailed. Just make Cyberpunk 2. No more V that story is dead.
My very pessimistic side fears it might possibly end up like this, with emphasis on the first part. To summarize, the game seeing its most urgent things fixed and remaining largely as is with some of the more underlying problems.
But of course I hope to be wrong in this regard.
I would generally categorize in three areas.
1) Bugs and technical issues that can be reasonably fixed in usually a short amount of time
2) Minor and major content additions and revisions that can be reasonably implemented in a moderate amount of time
(can also include refining gameplay features)
3) Re-doing key parts of the plot or core game mechanics that ... may be questionable because I imagine it requires a large of amount of work - it is therefore the most unlikely
Now, all of that including the unspecific time frames are subjective largely. Point being is, we can expect many things to change but they obviously can hardly redo the core of the plot. For those who might've hoped for something else, I mean.
We likely see 1 and 2 apply in that order throughout the next weeks, months, or year(s) until they - I imagine - positively surprise us with the next follow up game that surely will be perceived better due to a "learning process" and feedback collected throughout.
I don't want to post a massive chunk of text nor a huge list to state what I think would fix the issues in this game, so a few lines of text will do.
I think the apparent bugs and performance related issues need to go, cut / withheld / changed content added and the world itself would need more activities or types of activities. If I can, on top, get DLC that allow me to take a deep(er) dive with some (sub-)factions, even lemme sign up, while making the NPCs and AI more reactive to what I do and what I might wear, then I'd be happy and by then consider it a nice game all in all. In addition, some quality of life things like walking (even though a mod already cover it), sitting, a 'barber' or char customization at a ripperdoc and more clothing / gear.
The path until then, however, isn't anywhere about to end I feel, nor can you deviate from it too much because what's done is largely done.
My main hope is that they might attempt a new approach to tackling the next game, perhaps more akin to a classical RPG open world experience with some more choices and character customization.
