Ricoh's GRX is a similar concept, but there you change the sensor with the lens. I don't see a way for Nikon to monetize this idea, except if the "new-and-improved" sensors had outrageous prices.

Well it could just be for replacing the most delicate part of a camera easily, might not be for consumer use. Interesting though.

I wonder if you can do really high-res mono work with a mono sensor? It might be more commercially viable to sell a camera that can be con verted from mono to colour and back like that than to do two completely separate models?

What Martin says.

In addition to Monochrome sensors, I am thinking of Infra-Red sensors too.

Pretty much whatever film could do, this new modular technology would be able to do too.
