Yo team — if you're planning to play Kingdom Hearts on your Switch 2 this fall, start clearing shelf space because the official file size estimates just hit Nintendo eShop pages. After all those years of cloud-only ports being discontinued, Square Enix is finally dropping native digital and physical releases on October 8, and it's a massive win for portability! The whole collection is coming in two forms: an expansive Game-Key Card edition and the full digitial bundle. This means no more streaming — every title runs locally at higher fidelity.
Let me break down what you need to download because the numbers are eye-watering but exciting. The Kingdom Hearts Collection (I–III) alone sits at a massive 131GB, which is basically half your system storage right there! Each individual entry has its own footprint: Kingdom Hearts HD 1.5+2.5 ReMix takes up 54.2GB and's also on the original Switch; Kingdom Hearts III + Re Mind with all DLC comes in at 45.2GB, and the shorter chapter prologue for KH HD 2.8 is 26.8GB. You can stack every title to play through each generation, but be ready — installing even two of these consumes about a third of your available storage instantly.
And get this because it's still fresh — Kingdom Hearts 4 was confirmed coming to Switch 2 too and it will launch the same day as other versions when the time comes! If you currently own any of the old Cloud versions, they stay playable until June 9, 2027, but before then you should claim your discount on these new native editions. These are estimates subject to change by October, so watch for final patches near launch. The future is bright — this series has been a Nintendo favorite since day one and finally having it run natively at full speed feels like the series got its due.
