The Division 2 officially launches on 15 March 2019 and Ubisoft have confirmed that PC and Xbox One crowds will need between 48 and 52 GB of free space to install, while PlayStation 4 players will require as much as 100 GB post-patch.
Note that preloads have already started for Xbox One and PC players who bought a digital copy of The Division 2.
PlayStation 4 players from Europe who have Gold and Ultimate editions can start preloading immediately, but Standard edition preloading isn't until 11 March, 12:01 am local time.
The same deal in Americas means Gold and Ultimate start preloading from 10 and 13 March, 12:01 am EST, and same goes for Asia, Japan and Korea, except it's 12:01 am HKT/JST/KST.
According to Ubisoft's instructions, installation procedure on Xbox One and PlayStation 4 consoles is pretty much identical.
In both cases, The Division 2 will require Title Update 1, which weighs in between 48-52 GB depending on where you're at.
The game's footprint after the update, however, will be 90-100 GB on PlayStation 4, while Xbox One and PC will only need 48-52 GB for the game.
Ubisoft mentioned that the Title Update 1.5 for Tom Clancy's The Division 2 is coming already on 11 March 2019, and should weigh in at around 2 GB. "Title Update 1.5 mainly addresses occurrences of audio missing or cutting out experienced by some during Open Beta", they wrote.
It's also worth reminding that The Division 2 unlocks at midnight of 12 March for everyone, so if you're dead set on experiencing it absolutely spoiler free - watch out for Australia and New Zealand.
They'll be the first to start streaming so odds are that's where the first spoilers are coming from.
In their defence though, it's pretty hilarious and makes the scenario where Mexico builds a wall between them and the US a pretty believable one.
