So far:
The price ... Here of course the most "cool" development of Sony.
I like everything in the camera. There are some nuances, differences from the same a77-2, but basically the camera is also perfectly in the hand and works just as well.
Resolution and low level noise.
AF system, I use 24-70 CZ, Tamron Sp 70-300 USD and even Minolta 50/1.7 works very good with the camera.
The first thing I checked in the camera is AF's work. I'd not complain about the AF at a77-2, then AF a99-2 even better. I shot the series in AF-C mode - it's "strong like a rock". The person who wrote for dpreview camera review, or did not read the instructions to the camera, or simply hates Sony. Well this is his problem. And will remain on his conscience.
I made a report almost in total darkness. The level of the noise surprised. Very usefull ISO 6400. I have not played RAW files yet. And they are not particularly needed for the reportages. The JPG of the camera is excellent. Maybe I'll shoot something in the studio, then I'll spin RAW. For today, I do not see any reason to deal with RAW.
This is the first impression of working with a99-2. So far very pleased with the camera. Really wonderful professional tool. Maybe there will be some negative aspects, as without them.

But for today everything satisfies 100%, except for the price of the camera. Or maybe it should be like this, yet this camera differs sharply from Sony's previous models.
PS. Sorry for my english.
Oh! I know what I hate in a99-2 and a77-2 - joystick ! The thumb aches after use it. Very sharp edges.
