according to the supertesters, WG is planning to rework (in some case, heavily) certain maps, possibly in patch 9.6 (but this is not sure). These maps include:
Prokhorovka, Karelia, Steppes, Swamp, Siegfried Line, Live Oaks
Siegfried Line – the changed spots will be following – white lines show the changed spots:
Live Oaks – spot marked as 1 will be covered with houses and spot marked as 2 will have a small hill. Both changes are designed to make the north-eastern base harder to scout. Changes at point 3 are not known.
