Last week we got to learn that XSEED will be the publisher behind the physical edition of Shantae, but that is only for the NA version of the game, meaning as far as a Europ version is concerned, WayForward are currently without a publisher.
We have not announced a publisher for EU yet. This does not affect the target release date for EU digital.

Hopefully this will be rectified and a European release of a physical version will happen, even if we do have to wait a couple more months to get it, but for now it is uncertainty. We’ll follow up on this as soon as any more information develops.
