Interview of Evilly about polish tanks

Poland is the newest nation to be added to World of Tanks, after Sweden. The nation does currently not have a full tech tree, but a tier 6 premium medium tank, the Pudel. It's very possible that Poland is going to get a full tree though, because Wargaming was shown Polish tier IV meduim tank B.B.T.Br.Panc two years ago.
