With mere days until Christmas, it feels like the announcement and release of the inevitable Holiday DLC update for GTA Online will happen any moment now. However, much like in the case of Executives and Other Criminals, players are still leaking content even this close to release. It seems that the in-game models of a few masks that the update will be adding, along with the new vehicle, have been posted online ahead of announcement.
Part of the upcoming update's content was leaked alongside info regarding Executives and Other Criminals a while back, however this newest info dump holds some new surprises. Data-miners dug it up from the files of last week's DLC. It appears that Rockstar pulled the same trick as they did with Lowriders and the Halloween DLC, as the update you downloaded to get Lowriders contained the Halloween files, which were simply activated at a later date.
