Bad news, physical copies of the game have leaked ahead of time, so some people out there are already playing - and spoiling - parts of the game faster than hosting services can take the footage down. News first spread when someone posted a photo of a physical copy of Cyberpunk 2077 for PS4 in hand on the game’s subreddit. At this point it was hardly verified since these things can be fairly easily faked in this day and age, but then the person who got ahold of the leaked copy went and did a 20-minute livestream of the game’s opening sequence, running on the PS4.
This confirmed that the leak is legitimate and it was viewed by countless fans and journalists alike. It was initially hosted on Youtube before the service nuked the video for copyright infringement, after which the footage migrated to Google Drive. It was taken down there too, but once something is on the Internet you can never truly delete it - but for the sake of sparing fans any spoilers we chose not to link any live hosts. If you really want to watch the footage, finding it won’t be hard. If there are already complete and finished copies floating out in the wild - which also means that retailers likely have the stock in their warehouses already - we can safely say that the game won’t be delayed anymore. Why, then, do we need to wait until the 10th of December?
While the game discs are ready to go and are playable, as we can see from the leak, the additional polishing and tweaking the developers are using the remaining half-month for will be deployed using a day-zero or day-1 patch which is likely going to be a mandatory installation before playing. The reason the leaker can play now is likely because the patches themselves are not deployed yet.
Be careful online until launch - you no longer know when you can run into major spoilers! Cyberpunk 2077 went Gold (an industry term for the creation of the gold master disc holding a version of the game playable from start to finish) back in October and will be released on the 10th of December.
