continuation of the main story obviously. Fix the plot cancer, let me have agency and get a satsfying conclusion. I won't buy any mid-game or prequel DLC if I always have to think about my V kicking the bucket in the not so distant future.
All three endings where V goes back to his body can be relativey easy comsolidated into one quest chain.
I also really want the romance/friendships quest of the four LIs to be expanded both in act 2 and in "Act 4".
And It would be great if the Peralez quest could be expanded in the Mr Blue Eyes part of the DLC.
Regarding the fact that Cyberpunk is only he first game in the franchise and Witcher 3 didn't have any real post game DLC...
I don't think this matters in the end. Just because they went into one direction with Witcher DLC doesn't mean they have to do the same thing again. Look at the Dragon Age: Inquisition Trespasser DLC. It picks up after the main story, takes all player decisions into consideration and changes the game world, the future of important NPCs as well as the Inquisitor significantly. And it's beatutiful and rewarding. There is definitely some precedent for ending altering DLCs in the genre CDPR could emulate. And Cyperpunk is not Cyberpunk 1, it is a stand alone game that has to work on its own, especially after the lanch clusterfuck. DCPR can't bank on a sequel, they have to fix this mess within this game or give up on the IP completely.
