Great now everyone won't be happy until they bring out a 10mp version in a Z600 clam design ;P
Otherwise nice camera, hopefully it'll do well considering alot of the camera companies are facing losses due to large amounts of stock.

I just wonder what practical use will that offer  High resolution posters/billboards? Or simply to provide hi-quality digital zooming?

Digital zoom is pointless. People seem to be forgetting that light travels as photons, and no matter how many megapixels sensitivity the chip has, the quality of a captured image will not improve if we do not increase the amount of photons being detected by the light sensitive receptor. You can think of a photon as being a single "bit" of information; no matter how many bits of information the camera is capable of processing, the image quality will only improve if we increase the amount of light "bits" being received, ie by focusing more photons on to the receptor with a larger lens.
This is simple physics.

You forgot to mention that the "Particle Theory" is still a THEORY so it's also pointless to talk about it here IMO. 
When I mentioned Hi-quality digital zooming, it's just like taking a shot of something at 1024x768 resolution while your camera can actively capture 21MP this will be like cropping a 1024x768 area from a large 5376x4032 which is requires no interpolation in the part of the camera -- this achieves hi-quality. It's just my idea anyway so, no big deal.

I see what youre getting at but its not entirely correct. A 1024x768 area cropped from a 5376x4032 chip would actually contain less "light information" than an image captured by a 1024x768 chip with the same surface area, for example.
Its a bit like having bad reception on your car radio, you can turn up the volume, or you can extend the aerial. Extending the aerial will give better results, as you are effectively increasing the amount of information being received by your radio. In this case, increasing the resolution of the camera is analogous to turning up the volume without extending the aerial, you are still capturing the same amount of information.
As for the particle theory, light has particle/wave duality; it is both.

In your camera - radio analogy, doesn't this:

suffice as extending the antenna?
