WG developer Riot_guy on RU forum confirmed: developers are considering removing North-West map from the game, it's possible that it will happen even in 9.7. Other maps currently considered for removal are South Coast, Sacred Valley and Hidden Village.
And there's more. Kharkov is doing fine for now according to developers, but Stalingrad is going to be reworked.
PS: Anton "Evilly" Pankov confirms: no penetration nerf in 9.7
