Re: Summary of Article missed basic facts.. that even article has.

I agree with your nice summary.
I would ad one more variable and that is heat transport off of the sensor and out off the sensor house.

With the same sensor in two different bodies, the sensor with the lowest working temperature at the moment the picture is taken, will show lower noise than the other one.
So heat transport influences noise read out. Generally speaking, a smaller body will create more noise than a bigger body, with the same sensor.
SLT's create more noise too because the sensor is more active, as we need the sensor to feed the EVF.

So, as a consequence, the same sensor in an SLT body will probably create some more noise than in a DSLR body.
The fixed mirror in an SLT body prevent heat to escape when a picture is taken in the lens direction too, whereas a DSLR will evacuate some heat through the flipping mechanism.

So, as stated here before, there is more than sensor design alone that influences sensor noise.
It is the sum of all factors.
