Here is some additional information on the upcoming Samsung mirrorless camera with a black and white sensor I already mentioned last week: Samsung will unveil a new limited edition version of the NX300 mirrorless camera with a black and white version of the same 20 megapixels sensor and no low pass filter (similar to the Leica Monochrom).
The new camera will be called NX Achromatic and most likely will have a full metal body. I am not sure if the new version will be just for the Asian or few others select markets. The specs are not different than the NX300M with a new firmware and different "RAW shooting modes". The new camera will be offered as a bundle with one or two pancake lenses. Stay tuned for additional details.
Update: Nikon already has a 16MP full frame monochrome sensor.
