A second thought follows from the first. Ricoh might pursue its odd collection of mounts by making each a low-volume premium line. This would suit the 645D, the Q, the Limited lenses, and their relative small size. They're already doing it with the GXR and GRD (and arguably the Q). On the one hand we've got the great many-models, high-volume trio of Sony, Canon, and Nikon that they don't want to compete with, and on the other hand the existing premium brand seems to be struggling a bit. There's plenty of room in that space, I'd say.
I bet they've had a look at the remarkable profitability of a certain smartphone manufacturer and are getting thoughts.
