Quick answer
No. Nintendo Switch and Nintendo Switch 2 are listed as separate versions, and Natsume has not published an upgrade-pack, entitlement, or save-transfer policy.
Evidence checked
- Both Nintendo platforms are named separately.
- Both have physical preorder variants on Natsume Store.
- No cross-buy or paid-upgrade language appears in the announcements.
How to use this answer
Buyers should select the version for the hardware they plan to use rather than assuming an automatic upgrade.
The answer is scoped to Harvest Moon: Echoes of Teradea and the public evidence available on 2026-07-29. It does not import schedules, values, controls, item data, or progression rules from an earlier Harvest Moon game.
What remains outside the evidence
Separate listings do not prove whether a future upgrade option will or will not appear.
If Natsume, a verified platform storefront, or reproducible launch-day testing supplies the missing field, this page should be updated with the exact source and review date rather than silently replacing the earlier status.
