I won't criticize it since I don't understand the details. However, I do have some superficial hypothetical opinions regarding the idea.
1, From the short description it seems as if it actually choses to overexpose and takes care of the overexposed pixels via their resetting mechanism.
2, It sounds as a smarter version of Fujifilm EXR mechanism. Similarly as in the case of EXR sensor, one group of the pixels is used for capturing the shadows, the other group is used for capturing the highlights. But in the case of the EXR, membership of a pixel to either group is predetermined (the well known EXR pixel layout), while in case of the Rambus' BinaryPixel technology the membership is decided based on the actual exposure process taking place.
3, Practice has shown that EXR approach works in expanding the DR, but some sensor area is actually wasted. The Rambus technology essentially means you'll get the benefits of EXR without the infamous EXR drop in resolution.
Hugo808: So the advertising department gets to say it's a sharper camera because of the lack of an OLPF, which you wont notice unless you blow your pics up to 6 foot wide.
But no OLPF means you might get moire which ruins your pics permanently (no matter what they say). Are we supposed to be happy about this? I've waited ages to upgrade my D90 but I am not going to risk moire as I shoot a lot of weddings. You can hardly ask the bride to remove her veil because Nikon can't make a decent camera any more.
I think photographers should be put back in charge of camera design at Nikon. Or at least give us a D7100e which has the OLPF put back where it's supposed to be!
The fact is that with resolutions this high the risk of moire is almost negligible.
But you're right: weddings are a special case because of the veils.
Rachotilko: I don't understand people complaining over the sensor size, when it's actually IQ that matters.
Of course, IQ depends on sensor size, but it is not the only parameter determinig it. There is the technological advancement thing, which many forget about.
This device beats Olympus XZ-1 in IQ, and yet XZ-1 was such a spectacular success. I don't see why XZ-10 should be priced any less than the XZ-1 was.
There are however very good reasons to believe the sensor will be significantly better on XZ-10 than on XZ-1.
About the lens: yes, I think the lens will perform the same.
The DOF control on sub-1" devices ? C'mon ! Maybe for close-ups.
SX50 beating XZ-1 is no speculation, but the hard numbers. See DxOMark.
Regarding XZ-10: Yes, it's speculation, but given the current state of the technology and the market, the opposite outcome will be very unlikely.
Best 1/2.3" sensor of today (Canon SX50) beats XZ-1 hands down. There's no reason for XZ-10 to do any worse, when in fact both Canon and Olympus use Sony P&S sensors these days.
I don't understand people complaining over the sensor size, when it's actually IQ that matters.
This market segment does not deserve to survive.
Macx: More megapixels does not equal less resolution guys and girls. You HAVE to compare the final output. Looking at it on a pixel-per-pixel basis is meaningless in a photography context.
Now, I agree that 20 megapixels behind a comparatively tiny lens aperture sounds like trouble, and it obviously isn't marketed for enthusiasts, but maybe Casio uses the extra data-points for some clever automatic noise reduction and sharpening which is appreciated by the snapshooters this is marketed for.
Or maybe they just want to distinguish it from other P&S in its price range.
Hey, but what about diffraction ? Such a tiny pixels are more sensitive to the effects of diffraction. You can combat the resulting loss of sharpness by using larger apertures, but this thing has also tiny aperture: f/3.5-f-6.5.
BTW, this thing has CCD sensor. It's very well known that CCDs are particularly badly affected by high pixel density.
K_Photo_Teach: The Nokia 808 Pureview showed that high megapixel counts on small sensors can work.
Nokia 808 Pureview had 1/1.2" sensor => three times the area of 1/2.3"
It's hard to do simple things, but you've managed it !
ilya82: Got mine yestersday. The first thing I can say -for me this camera is a reincarnation of the legendary 5D :) Pictures has the same charm as 5D had.Very happy!
After reading your comment I've got a bit curious and went through DPR sample gallery of 5D. While the samples were certainly great visually, I am astonished how much shadow noise was present in higher ISO images in those days.
I like to first picture, really. The bright friendly lens actually smiles at me, inviting me to take photos through it.
Rachotilko: I want this ! This device utilizes the advantages of small sensor digicam in the best possible way.
It makes one wonder why devices like this one have been so rare ? Why the myriads of f/3.1-f/6 point&shoots and none of f/1.8-f/2.7 ?
Yes I know it's not cheap&easy. But the lack of XZ10-like devices is strikingly disproportionate to the diarrhea of f/3.5-f/6.5 "cameras".
magneto shot: hmm set aperture to 1.8 , shoot picture of portrait standing 5 meters away...no blurring of background, no bokeh....set aperture to 2.7, shoot picture of portrait standing 5 meters away, no blurring of bg, no bokeh
whats the point of small sensor again?
The adjectives "bright&fast" have to do primarily with light throughput and - implied - fast shutter speed. The bokeh and background blur are nothing more then a (pleasant) byproduct.
BTW, there is much more to photography than the "bokeh" eyecandy.
I should have been more specific: I meant the 'sub-1/2" sensored, pocketable in the strict sense of the word' category.

brianj: Interesting, it has the same size and type of sensor at the canon SX260HS, yet has not got as wide angle nor anywhere near as much zoom. Ah, I see, its called enthusiast because it sports a f1.8 aperture lens.
I wondered what the name 'enthusiast' meant!
pity I can't assign more than one "like" to your reply ! I really wonder why is it so tough for many to grasp the benefit of low ISOs enabled by fast lens.
To balance the negative comments: I have bought G3 recently and enjoying it tremendously. I especially like the great viewfinder and AF speed.
Thank you, Panasonic !
Timmbits: Proof you don't need to make a compromise on sensor size in order to have a reasonable sized package. (re: page 3 vs. gx1) Makes you wonder why they came out with MFT in the first place.
Size of the lenses maybe ?
dpfan32: Funny no one is discussing the XZ-10 :)IMHO they took a too small sensor.To provide better quality than an iPhone 5 they need something like 1/1.7" or bigger. 1/2.3" can't shoot significant better photos than a good smartphone camera (not to mention the 808 PureView)
Unfortunatelly I haven't seen iPhone5 shots, but here's iPhone4S:http://www.imaging-resource.com/PRODS/IPHONE4S/FULLRES/IPHONE4SINBFL.HTM
And here's how a good 1/2.3 sensor crushes it:http://www.imaging-resource.com/PRODS/FZ150/FULLRES/FZ150INBI0200.HTM
