here we go - finally the origin of new 16mp m43 sensor is known (or is it ?)

I read the datamatrix barcode found on the Sony sensor image you posted here:

it reads :

​18M128031-040000420107821 when the markings on the chip are IMX128 and then AQP

and now the EPM2 markings:

​26M109123-2000140238P6MM1 when the markings on the chip are M109 and then AQE

​Do you see the pattern? First the type of the sensor then the serial number followed by the error checking code (last digit). It seems like Sony to me.
