You might be "happy" to know that the VK2801 gets nerfed. Specifically: its depression gets nerfed by 2 degrees from -10 to -8 and the 105mm HEAT shells get the same nerf penetration nerf as the Panzer IV - from 150 to 104. Furthermore, the 105mm shell price is changed also: the 105mm derp shells (for all vehicles) get twice as expensive (from 60 to 120), with the HEAT shell price moving from 7g to 10g.
Aufklärungspanzer Panther gets buffed tho:
It's MM weight gets reduced (from 32,4 to 27), it gets 50 HP more (from 950 to 1000), but the price will increase by 40k. Tracks will get a slight HP buff and the Konish will get an aimtime buff (from 2s to 1,7s). Furthermore, the Konish silver ammo price will be halved.
Oh yea, and Leopard 1 (apart from the 20 pen nerf for HEAT shells) gets better MM weight too: from 120 to 100 (the MM weight for E-50M stays at 120 tho).
