what many suspected is now confirmed – German tanks are getting split in 9.0
Tier 3 will be Panzer Ausf.A
Tier 4 will be Panzer Ausf.D
Panzer III is going to also be split into two tanks and StuG the same.
Edit: Panzer III might not be split after all – the older model will apparently somehow merge with Panzer III Ausf.A
