Whether DXOLabs ever tests this camera (or do it before it ceases to be relevant in the market) or not, you have plenty of thorough reviews out there to guide you. The sensor, important as it is, is only a part of the equation. And we already know it is outstanding (those of us who own this little camera have no doubt of its capabilities).
But the camera offers much more (take a look at DP Review, for instance). It has a very fast autofocus, can shoot 9 fps, has an extraordinary stabilization system. The viewfinder, while having less resolution than that of the NEX-7 or A77, is far more "natural" in actual use and with an excellent response time. There are tons of little extras that often don't get mentioned in reviews, but that we the users greatly appreciate. For instance, the fact that it stabilizes the image in the viewfinder, not only at shooting time (great for composing and focussing in manual when using a tele). Lots of little things like this which makes it the best CSC camera in the market today.
So what DXOLabs can tell us that we don’t already know is where in the sensor rating scale, this camera falls in. All else at this point is stale news. IQ is just superb. I use it mostly for landscape photography and I am very pleased with it. People who use it for street shooting or even photojournalism say wonders of it. So if DXOLabs ever tests this camera (and I’m beginning to think it won’t because soon it will become meaningless anyway) I’ll be willing to bet it will be somewhere in the range of the NEX-7 or even a little higher up in the scale. The fact that Sony has been officially declared the manufacturer of the sensor comes to no surprise to me and makes a lot of sense.
My suggestion is that you forget about DXOLabs and test the camera on your own, to see if it lives to your expectations. You ought to do it regardless, anyway.
