Xenoblade chronicles 3 Switch 2 Ediiton.

Just a small question regrading the switch 2 edition.
On the eshop, the upgrade says its releasing on the 1st October 2026
But the actual switch 2 edition says its releasing on the 3rd of December.

I am a bit confused. Will the upgrade pack include the switch 2 features like the increased fps and resolution and is just releasing earlier because its a download code not physical?
