Why not just a 12MP sensor with 2.4µm sensor size then? It is the reverse of what was going on 20 years ago, upscaling a low res sensor to produce a high res picture, now they are downscaling a high res sensor to produce a low(er) res picture. It is not as if the raw output can be used at full res anyway due to the tetracell filter in use, software still have to "fill in" the missing color information.

CM1 is the best camera phone I ever owned, and that "only" had 20MP, but on a 1" sensor with Leica lens. It was so good that I went and bought a Canon G7X when it became clear that Panasonic is not making a CM2.

It's quite obvious that the higher density of photosites will help enhance resolution (and provide potential for one shot HDR), even if the CFA yields (relatively) lower color resolution. What I really can't guess if whether 108MP nonacell binned to 12MP has an advantage to tetracell binned to 12MP, i.e. is a CFA in groups of 9 worth it, or is it really just a readout difference or even software difference.

I am excited to see how much noise and grain is there in low light photos and videos with this!

Do not forget that having just different binning does not help acquiring the light, it mostly helps denoising, colors and shutter speed will not increase if the tech is the same,  as opposed to usage of ryyb or other on sensor improvement as seen in xperias that reach the fastest shutter speeds.
It will be way better but not compared to mate30pro.

Ultimately this sensor is larger, and that should bring most of the performance improvements, unless something turns out seriously wrong with their processing, which can't be completely ruled out yet.
The 4-1 bin HMX's 27MP output, downsampled to 12MP, could be more or less on the same level as this sensor, unless they make full use of this new binning method and use 3 different readout speeds for each group of 9 photosites, or something. Merely binning on the sensor level yields poor results, a full readout with intelligent downsampling occurring in the ISP maximizes utilization of the data, but that taxes the ISP to a far greater extent, of course.

Having a wider sensor probably means shutter speeds can be dropped too. No need to keep it open for longer when the sensor is now much wider and can collect more data.
