Call of Duty: Modern Warfare 4 Receives Major Switch 2 Update and Storage Details

Call of Duty: Modern Warfare 4 has received a new update on the Nintendo Switch 2, with user reports indicating a download size of around 39GB. According to available details, the post-update installation size on the console reaches approximately 91.3GB, which largely replaces existing files rather than significantly expanding the game's overall storage footprint.

This release follows the game's October launch, marking the first new series entry on Nintendo hardware since 2013. Activision has also published patch notes for an update rolled out across multiple platforms, addressing stability issues, crashes, and specific bugs in modes like DMZ and Search and Destroy.

Storage Implications for Switch 2 Owners

• At roughly 91GB, the game occupies more than a third of the Switch 2's nominal 256GB internal storage.
• Usable storage is lower due to operating system reservations.
• Players can expand capacity using microSD Express cards up to 1TB, as 2TB cards are not yet commercially available.

Industry Memory Constraints

Industry forecasts suggest that 2TB microSD Express cards may face delays beyond their expected mid-2027 timeline due to ongoing NAND flash supply constraints driven by AI-related storage demand. Current 1TB cards suitable for the console often retail for over $300.

Practical Implications and Verification

Players should verify available internal storage before downloading updates. Official patch notes and announcements can be verified directly through Activision's official support channels and the Nintendo eShop.
