apparently (although this info is NOT confirmed), Wargaming is working on a new (yet unnamed) map, code name “the pit” (or “the hole”).
This new map is very small (400 x 400 meters) and is allegedly being made especially for low tiers (1,2,3). The reason behind it allegedly is that Wargaming wants the new players to “feel the action” straight from the start, because the fighting starts very soon after the battle commences and the fighting distance is very short. The spawn points are allegedly at the south and north of the map, the bases are in upper right and lower left corner.
