I just dug up more stuff thanks to a lead on 2ch. The animation character designer is probably Kyoji Asano, and the production of the show will be handled by Wit Studio.
Wit Studio is previously Production IG Studio 6. IG Port officially turned them into their own studio in April this year:

Asano's Twitter profile confirms he is working at Wit Studio, and he also retweeted the Psycho-Pass news:

Edit: It turns out that Shiotani and Asano have worked together multiple times in the past. Asano was the Animation Director for Chevalier ep18, Sengoku Basara ep2, and Tokyo Marble Chocolate (he was the sub character designer for that too). Those are all episodes which Shiotani directed. So it definitely makes sense that they would work together again on a new series.
