Douglas, I see your point but I don't agree completely.. The M9 sensor it's like the one in the M8, only bigger. It doesn't seems to be greatly modified ( apart from not needing external IR filters ).
Of course the angles of incidence are more problematic on a FF sensor but we'll use longer lenses in the FF to have the same FOV of an APS-C camera .Say a 24mm in APS-C vs a 35mm.in APS-C. .( or 16mm vs 24/25mm ).The question is if a ZM35/2.8 on a 'possible' FF mirrorless would perform worse or better than a ZM 25/2.8 on the GXR A12 M mount.
I'm convinced that if Ricoh wanted to release such camera it won't be a technical problem for them to have the same performances of a M9 or even a M240 for a lot less money than $7000.
Of course they'd need a Sony sensor tuned to their specifications, more expensive than the 'ordinary' 24 Mp sensor of a Nikon D600, but there's a huge price gap between a $2000 D600 and a $7000 M-240.
Nevertheless, I don't see that FF Ricoh appearing in the immediate future and possibly never. My bet is that they have decided to let die the GXR system in a slow and painless way.

Leica had to further optimize the M9's sensor to deal with oblique light rays, simply because of the larger sensor size and thicker IR filter. The GXR M still isn't exactly perfect with M lenses, which is why they built-in the color fix option in the software, and, in fact, I'm not totally convinced that Ricoh did much to the Sony sensor at all, outside of removing the AA filter. All sensors have "optimized" microlenses in one way or another, and I'd bet it's mostly Ricoh marketing. Not saying that that Ricoh, or anyone else, couldn't make a sensor that works great with M lenses. I just don't think Ricoh really has much of a lead on it over anyone else.
