I think they should get a new sensor pronto before they release this thing.
I,briefly, tried the camera a couple of weeks ago and found nothing really lacking in the file.
Files were excellent but no better that Leaf,Phase, or Hasselblad.
In use, the camera, physically, felt more comfortable than any other 645 based body I've owned or used.
I just don't think they are going to sell enough to sustain the line.
Certainly can't see many, if any, migrants from existing entrenched DB systems and while there are certainly going to
be a few Leica personalities buying into in, because that is what they do.
There seemed to be a little groundswell early on from M / R users, with no medium format experience, who wanted the best possible file
but with the surprise release of the FF M9 many now seem to have re-allocated funds to the M line.
