OpenPGP Card ECC status?

there was a little henn-egg problem with the card specification in the past.
I published a beta version with ECC (partly) last year, but the related standards (ISO 7816-x)
were not finished. As in the past I plan to be as close as possible to international smart card standards
because all somming products will follow them and there is no chance to get proprietary functions/algorithms
in cards on the market.
Most important for future cards will be EN 419212 (Application Interface for smart cards used as Secure Signature Creation Devices),
that replaces the discarded EN 14890, that I used in previous versions of the OpenPGP card spec. This standard is ready now and I plan
to finalize the OpenPGP card spec soon. I still need some help from Werner for defining the dec-command, because this requires a special usage of ECC.
sign and auth is clear at the moment - all new standards only support Brainpool, NIST was stripped of from all papers after the NSA problem last year.
Key import for ECC is also described in new ISO 7816-8 (not ready, but stable enough for usage).
After finishing the spec we can do test implementations and after that GnuPG can be finished in that direction.
