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.
