We shall see i guess. Its pretty much all speculation tbh since we know very little about the plans moving forward. Dont think it will be bugfree for years too come tho, hopefully they fix the worst issues soon atleast.Playing it without bugs is pretty much like playing a whole new game I imagine.
Console people got royally shafted. I bet you many people couldn't even play the game properly before bugs cut their play-through short. I'm on PC on this patch right now and I still have gigs I cannot finish, perks that are broken, gigs that don't trigger. Not to even mention the bugs I used to have like Dum Dum vanishing or jackie vanishing.
That doesn't even take into account new people who I've seen make posts here on the horrible bugs on PC that still plague the early game. Many people I personally know said they skipped the game entirely and are waiting until the game is relatively bug free before they pick it up again. A next gen version could be the perfect incentive.
Like CDPR even mentioned themselves it'll never get to what it once was when it comes to sales, of course.
