The Pixel War is winding down and over for some... now the DR war begins.

Different shutter speeds for different areas of the frame in a single exposure, zoiks!
More or less just a software workaround, and not really an improvement in physical capability of the sensor.

Manufacturers are always looking for something to drum about.

He is talking about turning individual pixels on and off -- isn't that how QLED TVs work to attain their excellent black backgrounds and black color? They turn the pixels off so the LEDs are not producing any light, thus no image. If this is the way it will work, the technology has been around for about three years in a commercial application. Now, it just needs to shrink that 85" TV down to sensor size!

Currently only available for a 12 MP security 1 inch sensor, but interesting. I wonder if it filter to the kind of cameras we use or if it will be like near field photography that never really went mainstream.

As @Wallen said above, this is more of a control improvement than an increase in dynamic range.
It is still interesting, and will still 'get more DR' out of any sensor it is applied to.
It is not pixel level but 700+ areas of a 12 MP sensor.
None the less it is a step in the right direction and potential progress.
An interesting development for special application cameras at this point (especially security/ surveillance cameras)
That is a growing and profitable area for Canon
I think the real breakthrough is deeper pixel wells, which hasn't been easy to crack

Pretty much so but the other way around.
"On" time and brightness signals are sent to pixels in the monitor to give light, whereas it is only "on" time signals that is sent to the sensor pixel to limit the light/brightness it receives.

I don't think it would go mainstream as it would be taking lower resolution and HDR images all the time. Unless the user plans on editing everything, or they provide a very good normalizing filter, it would always look unnatural.

Making a sensor sensitive to see in the dark will always overexpose when it is bright and making the sensor limited to expose for highlights will make them useless in the shadows. Being good at both ends that are opposing in nature is in my opinion impossible, unless they stack 2 sensors together, just like our own eyes with cones and rods.
