I wonder how advanced the AI is or if support for rudimentary ray tracing ...Yes. 505 Games has been confirmed as publisher (summer 2020):

I've been trying to find out how big the meta game after main story is myself, haven't been able to find anything yet. But it seems logical that one should be able to continue to rebuild society after the main story. Much like MGS5.
Edit: and yes, it is considered a "big" game, with main story completion at up to 70 hours. Sounds very much like classic Kojima world building.
