They will supposedly be named the Loxia line. No rumored specs yet and of course many are upset they are manual focus only. If it keeps the size of the lenses down while providing some larger aperture "Otus like" native goodness then I'm all for it. Outside the 55FE I generally only use Contax or M glass anyway.
