If I get this corrrectly, the image projected onto sensor is reversed true image.
Then potential "light source" would come from upper left side (when looking at camera from back).

Kinda looks like light spot from single directional source at narrow angle.
If you have IR/UV filter removed, then it could be IR radiation from some component inside the camera, something that belongs to screen circuitry. Sometimes voltage stabilisers or voltage reference are made with LED sources.

If it's 600D, then I find it unlikely to be screen itself - screen is articulated and separated.

*I guess there is no IR detector below VF*

Noise performance is noticeably better than 7D.
Maybe I'm wrong but 60D/7D noise @ ISO 3200 is similar to 7D2 noise @ ISO 12800
Canon sample pictures, eh? 3200ISO on 70D (portrait sax guy) was clean as a whistle, real world images are far from the truth. That squirrel at 3200ISO look pretty good, but 1- its daylight and 2- Canon sample pictures.

Still, you are saying 7D2 has 2 stop ISO advantage over the 60D. that's ludicrous.
3x NO
I checked samples from other sources. I'm not sure if they want to be mentioned here.
As I said "noise will tell", and now it does... at least for me :)

Sounds interesting.
I wonder how fisheye variant of it would work out.

LOL...
And I still remember Nikon commercials, where they used pictures and videos of Canon gear, and videos specifically made with Canon gear to advertise Canon gear :D :D :D

CPL won't work to cut out reflections with non-polarised light sources.

This is actually incorrect. Light reflected at a shallow angle from certain surfaces including glass and water is always polarised - regardless of whether the incident light was polarised.

You may be thinking of cross-polarised lighting, used as a studio technique.
At this point you're just as not precise as am I. ;)
It's not about "certain surfaces", but transparent medium and certain angles for certain wavelengths determined by index of refraction.
So.... polarised reflection from non-polarised source: with water/glass - yes, with metal - no.

CPL is about sunlight.
When light from Sun comes to Earth, it is being polarised in the atmosphere.
Direct sunlight and luminance of clear sky are polarised.
That's why polariser can cut out most of specular reflections of sunlight and from sky.

CPL won't work to cut out reflections with non-polarised light sources.

That's what you do in industrial espionage - feeding with different types of bs each suspected groups/ppl separately and see what info would leak.

If "Lens Electronic MF" means "Lens Electronic Manual Focus" I imagine that it could be manual control of focus using electronic controls in body... Perhaps "Follow Focus" function in body itself?
You don't flip switch on lens to "Manual", just to electronic override.

One moment you use DPAF in video shot, and when you want to take over focus, then you could do it at any point, and get back to auto seamlessly.

Yes, yes, I have read it.
But does it work in video? What controls you use for manual "by wire" focusing? Why USM only?
I wish I had the opportunity to check myself, but reviews I read indicate that this "focus by wire" from 1DX and 5D3 aren't even half way towards manual "follow focus" functionality. Perhaps reviews were wrong, but I haven't seen follow focus accessories being replaced in 1DX and 5D3 setups.
I've read about touch control for aperture in 5D3. I imagine this could be done for 7D2 + touch control for focus.

Perhaps this "new technology" in 7D mk2 sensor can also mean different layout in sensor circuitry? Hopefully that would lead to lower noise.
I read somewhere that Canon sensor itself is not inferior to Sony offerings in sensitivity, but reading signals from sensor introduces significant noise, and that explained slightly higher noise in 7D compared to 60D with same sensor.

1)  Northrup's "sports test" was a joke.  Heck, even his wife (? I assume she is) called it a 'moving portrait'.  As I stated, a ~60% hit rate in that scenario is ridiculously low – something I'd expect even an entry-level dSLR to beat in that 'test'.  It's already been pointed out that he had a setting enabled which Canon warns against using with moving subject. 
That guy shamelessly admits inability to use proper settings on Canon, and sells it as a Canon fault.
If some of you are unaware, he also uses psychological salesman tricks. Entire video is made in a manner of shopping channel, like it's all scripted.
Guy has a role as knowlegeable expert.
Girl has a role of an observer waiting for answer, someone with whom viewer should identify. She gets convinced, that's that.
"How can you not agree with her you weirdo?"
