If you're not playing the full game, the update will be a monster.
Call of Duty: Warzone is set to stay on the Modern Warfare engine throughout the Black Ops Cold War era and beyond, with sources stating that even during the Sledgehammer Games turn (With Call of Duty WWII: Vanguard) Warzone will not switch engines.
With this, Modern Warfare is likely to be the application that many players will access Warzone through, although this may become a huge problem. Further updates to the title, despite the game being nearly two years old, will see an addition of 81GB added to a monster update.
As the Black Ops Cold War Season 2 Reloaded update was rolled out on Treyarch's engine (with updates varying between 7.4GB to 14.2GB depending on the platform), Warzone has held back on theirs slightly.
In a patch that will see new operators, a fancy ZRG 20mm Sniper and some fancy bundles added to Warzone, the update is set at either 52GB (for PlayStation 4/5), 57GB (for Xbox One / Series X|S), or 52.4GB (PC). However, for the latter, the update will amass to 133.6GB should they have Modern Warfare still installed.
The developers outlined in the patch notes that "the Warzone download is a larger file size due to the optimization of data" in comparison to the Black Ops one which was significantly smaller.
Raven further added that "players can choose to uninstall/remove other data packs if they are no longer needed for a smaller overall file size. Remember, the Warzone download is not necessary if you are only playing Black Ops Cold War and vice versa."
With an extra 81GB to a game that is out of rotation, it's hard to see why you would keep it installed. Still, the 50GB plus sizes for Warzone should not be discarded, with them still being monstrous.
One can only imagine the update size when Verdansk is finally nuked and a whole new map is added...
