Every Sony Zeiss is a Sony design. But, they will still follow some Zeiss design conventions. The Distagon will still be a reversed teleprime with another element (its why corners are a touch soft but the centers are amazing), and the Tessars are always simple 4-element designs with flaws, but tend to be lighter(24-70/4 is an excellent example of Vario-Tessars) and have great contrast. The Sonnars are the more unique one, as they are bright (wider aperture lenses) but do have a design pattern. The ZA 85/1.4 is a Planar design, it is incredibly sharp, and can have issues with CA (it does, but unless you shoot artic black dogs, it won't ruin your life). The Batis is a Sonnar and could really be anything. But if it just a smaller version of Sony's ZA135/1.8, it will be amazing. Once the lens design is out, we can see. But who makes it will have less affect than design.

Joshua, let me make my question clearer: we now know that the Sony-Zeiss FE lenses were/are designed by a Sony team, and are badged Zeiss. My question is: was that also the case for the ZA 85, or was it then designed by a Zeiss team? If it was designed by a Sony team like, say the FE 55 or 35, then I expect the Batis to be substantially different from the ZA 85.
The Corners on Hollywood 28 f2 is a nightmare on A7.. even stop down to f11 it is not good
( it never gets really good)
But it is a special lens which I love anyway .. to close-up is awesome .. sometimes with messy bokeh wideopen

Just a little bit of a background. My first Sony A-mount lens is the 135mm f/1.8 ZA. I was really impressed with it but it is bulky and heavy. I noticed some loCA in contrasty boundaries and out-of-focus zones but it can be minimize by the defringe feature of LR. I bought the 85mm f/1.4 ZA locally almost a year ago. Since I had the chance to handle it and I found the weight and bulk of the 85ZA to be just fine. The loCA of the 85ZA appears to be approximately the same as that of the 135ZA. From what I could gather from a few images of the Batis, it does "suffer" from bokeh fringing, as well. Unless, they incorporate an Apo system in the design, this "flaw" seems to be typical for fast short tele lenses.

Phillipe, the circumstances were not clear, at least not to me, since the ZA line was not popular. At least not as popular as the FE line it is now. Definitely the A7 cameras have garnered more publicity and a lot of folks are paying attention and are writing/reporting the circumstances more so than before.
While I am not expecting the Batis to be optically different, the advantage of this new line is clear. A noiseless AF system and smaller/lighter lens without the need of having an adapter would be those factors. I like the faster speed of the ZA and possibly a smoother bokeh though .
Werner...love the last bow shot with the 55.
Michiel..the purple wall flowers is awesome!
Ronny...great shots as always.
Pepjin...really enjoying your Tokina 60-120 pics. Is it a FF lens?
Here are a few more pics from the Santa Cruz Boardwalk! We tend to go pretty often. When you have season passes, and the park is only 15 min away...

You should really try that lens on a film camera body like Contax RX to see if there could be any improvement with a Kolari sensor stack modification.
