Hey @bmartins
EdDSA support for OpenPGPCard is available, as listed here. Nevertheless gpg support for ed25519 is kind of dicey, but generally it should work, please report issues you find to the linked repository.
About the Secure Element: we are currently in the process of releasing the first (test) firmware with activated se050 and minimal functionality to find out if we see any weird/unexpected behavior on devices in the field. The OpenPGP implementation is mostly “functional complete” and we plan to have this released before the end of this year - as always this will strongly depend on the following weeks (how severe the bugs are, which are found in the test-released versions).
