This will not happen soon. RH was given the permission from the NSA to use the NIST curves. Most of the EC curves have patents (Certicom) on their speedup implementation. The NSA acquired the rights for the NIST curves from Certicom, if I am not mistaken. So RH will only ever provide the NIST curves, until the legal situation is clear.
