The verified update
No. Natsume has announced five platform families but has not announced cross-save or save transfer between them.
This briefing isolates one part of the public record so that a player can act on the confirmed detail without mistaking a broad trailer, preorder listing, or product page for a complete specification.
What the source establishes
- Switch 2, Switch, PS5, Xbox Series X|S, and Steam are confirmed.
- The press releases do not describe account linking.
- No platform-to-platform save migration rule is stated.
Why it matters now
Choose a platform on the assumption that saves remain local until first-party store features say otherwise.
For editorial tracking, this topic should be reviewed again when Natsume publishes another game-specific release, when a verified platform store exposes new metadata, or when launch-day testing can answer the remaining operational question.
What this update does not establish
A simultaneous release does not imply shared progression or transferable saves.
No unannounced feature, value, route, schedule, performance target, item table, or story outcome has been inferred. The distinction is important because the game is still unreleased.
