Kenji Kamiyama and Yoko Kanno are not seemingly involved which is a disappointment.
I was super excited about a new GITS series until I saw these two details. Without those two, I don't think the chances of this working for me are good.
In contrast to the OP, I hate the GITS movie--it's so terribly paced, though I agree the philosophy is good, it just doesn't have a well-written story to hang itself on. It's SAC and 2nd GIG that are really firing on all cylinders, IMO.
