Shouldn't the question really be "When do you think Photomechanic will add support for the new OM System (Olympus) OM-1 Camera?"
Actually, I'm curious as to why the support isn't instantaneous. Is the internal structure of the OM-1 orf file different from all of the other orf files. PM can read (at least some) of the metadata but it can't render the embedded jpeg. Do you have to reverse engineer the structure of every new raw file that comes along?
