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.
Read the Canon sensor is unique in that all the exposure is at the same time.
All other HDR sensors do a cpmposit of several quick shots that if the subject moves there is blur.
So this is a new technology in obtaining the HDR in one instant shot per the written explanations out there.

Yep, as ive posted previously, "instant HDR".
What I understand is that they use a matrix, like the Bayer, but instead of certain pixels responding to a specific color, some pixels are meant to under expose so they are able to record blown areas.
This enables the instant HDR to happen but limits the resolution at the same time. Meaning it produce lower IQ images/video that is better suited to security cameras and not fine photography.

My very first digital camera 16 years ago was a Fuji S3 Pro. Its sensor had 12 million pixels. They were of two types, optimized for low luminance and high luminance. The sensels were paired and produced a final 6 MP image with somewhat extended dynamic range.
The camera produced very nice images, but it was very slow, and the user interface was very much cobbled together. Battery life with 4 AA cells was very poor.
24 stops of dynamic range will require at least 24 bits per pixel to save and communicate. That's at least 50% more memory and data transfer than today's best cameras. The key question will be, "Is it worth it?" and worth it to who?
To me, this is interesting but not exciting.

If they find this a leverage they can push through, it will be another field of battle from the major manufacturers. Might be the next big thing after mirrorless, or maybe not...
