Remember, in February, after 9.22 comes, there will be no more tanks left to be changed to HD. Only took 3 years. Future changes to models will occur though, mainly to change tanks that are „too bare”. The tanks made in HD between 9.0 and 9.3 will also receive updates (T-34-85, T-54, Panther, Tiger I, Maus, M4 Sherman, M18 Hellcat, M103, Centurion Mk. 7/1, Tortoise, IS, SU-100, StuG III Ausf. G, Churchill I and others).
In the 188.8.131.52 micropatch, the Ke-Ni Otsu was made into HD. Here are some pictures:
