some more info on the gameplay & perk system and so on, some leaked footage, and the full map:

So far...not impressed :what3:
Full map looks pretty good, especially since you won't have access to vehicles + the map will be densily cluttered either way.
I much rather prefer a smaller but more detailed map over a bigger map with nothing in it, like MGS 5 Phantom Pain's pathetic excuse of an open world.
