• Canon has used 130,180 and 500nm processes that I'm aware of. I would fail to see the reason why Canon would upgrade some equipment to an interim step of 300nm.
• The read noise of this is far worse than for instance an 80D sensor scaled. At worst case, this sensor should be no worse than the 80D sensor, as it's the same pixel pitch as the 80D sensor. The DR matches the 6D Mark II DR curve and not the current generation 5D Mark IV or even 80D DR curves.
• It is exactly like the 6D Mark II DR curve.
• It's too slow (even by Canon standards) 5.2 fps at 12 bit depth means it would be around 1.3 fps at 14 bit assuming it's using slope ADC's (which canon uses). Canon releasing a 1.3 fps stills camera? Not only that but DPAF takes around twice the read time so if you want AF you're looking at .6 FPS or a glorious 2.6 fps in 12 bit ("speed mode")

As usual Andrew from EOSHD made lot of hype out of nothing, finding old sensor specs made for some partner and not for any consumer cameras.
