You apparently don't know you are wrong. Maybe German tanks became obsolete in 1941 on Eastern Front but it does not mean such situation persisted till the end of war! In 1942 Germans introduced Tiger tank which outclassed all Soviet tanks (T-34, KV, not mention about older types) and in 1943 they introduced Panther tank which solidified III Reich qualitative advantages over Soviet Union in tanks. Later Soviets tried do catch up Germans in this area by fielding T-34/85 and IS tanks but I don't think they were successful. Anyway Soviets chose to vastly outnumber Germans in tanks and they really achieved this goal. That is also why Soviets won that war.
