Wargaming are testings black versions of Tirpitz, Asashio, Atago and Massachusetts. These will be identical to the existing versions of these ships except for an all black camoflauge which carries additional bonuses over the camoflauges that come with the current versions. These will likely be sold for more than the existing ships(although a black friday sale is highly likely) and as such is a blatent attempt to get more money from ship collectors. WG could very easily just sell the camoflauges seperate to the ships so they can a reasonable price to those who currently own the existing versions.
