Not too exciting - Sigma will provide L-mount versions of their DSLR-centric ART prime lenses.

I'd be very excited if Sigma came up with 11 Z line lenses. From a practical standpoint, 11 available lenses for L-mount are more exciting than 20 lenses on a roadmap which goes to 2021 and contains a couple of doublets with different apertures.

Best of it: If I'd lean towards Panasonic or Leica or the upcoming Sigma FF Foveon sensor, I could just get my lenses adapted to them. That won't happen tomorrow, but I must confess, I'm fed up with waiting for lenses and firmware updates. Nikon is too slow.
