Tomorrow we might finally get a taste of what Rockstar has in store for us going into 2017, as well as how much merit there is to one particular kinda-leak/kinda-prediction about the future of GTA Online DLC. Whether it's a tiny update, a proper DLC or just an event with no new content, it will likely set the scene for months to come.
So why are we expecting something to happen tomorrow, in lieu of any kind of announcement? Simple, Rockstar is a creature of habit, and over three years of running GTA Online, a few easily recognizable patterns have emerged.
One golden rule, so to say, is that the game almost always received new DLC on Tuesdays. Be they major updates or just small intermittent mini-DLCs that toss in a car and maybe an Adversary Mode, Tuesday was always the scheduled launch.
