I have low expectations for multiplayer, I think they are just so far behind on that, and it was always supposed to be years out.
I'm super down for some expansions though. There were always holes in the map waiting for DLC content (I know people think that was stuff cut for time but I think they always planned for DLC). I put a good 70 hours into Cyberpunk, and some meaty story DLC sounds real good to me.
Putting a 3rd person view and allowing you to change your appearance anytime during the game would go a long way. If modders can do it then the devs can.
Modders have pretty conclusively proven why third person would take a lot of retooling. It's not like that shit really works.
Next gen version is set to release this year but might be delayed.
TBH I hope they do not spend too much time on NPCS, police, customization and so on. It's all superficial stuff and I'd much prefer they would work on new stories, quests and characters, this is their strong suit and all those elements are already magnificent in the base game
Some actual AI for cars would be nice. They mostly avoid missions where this really matters but it would be cool if they didn't have to. The few where you do have real chases are ridiculous because the enemy cars can't even drive and have to teleport around behind your back.
