Hello everyone,
大家嚎， 

according to supertester sources, the next premium tank to appear on the supertest is Object 244, tier 6 Soviet heavy premium tank. Object 244 is this:
根据超测服的消息来看，下一辆出现在超测服上的金币车是244工程，是个苏联的6级重坦。244工程就是这玩意：

That’s right, it’s a tier 6 clone of the IS (tier 7 tank) with 85mm D-5T-85BM (the 144 pen gun) and slightly different suspension. Because, you know, this game definitely needs more pure clones…
没错，就是把IS（7级那个）复刻一遍之后装上D-5T-85BM（144穿那个）丢在6级，悬挂方面有一点点不一样。你看，这游戏还是需要很多很多复刻车的…… 

Also, as predicted, the Mauschen got somewhat nerfed, especially:
