I would think that if I had been in charge of the German AFV production the first thing I would have done would have been to get rid of the flimsy PIII and switch to only the PIV while pushing development of a successor similar to the Panther .
With the resultingly larger number of IVs in service the Soviets would have more pressure ,not enough to give the Wehrmacht a war winning advantage but enough to extend the war and leave more men to fight later .
Meanwhile the experience of fighting Soviet tanks would lead to something like the Panther ,only with sloped armor from the outset .Production would then switch from the IV to the new V tanks while the chassy of the IV would become the focus of development of tank Destroyers and self propelled artillery vehicles ,plus new airfcraft .
These changes would not win the war but would result in a better Wehrmacht with more ,better tanks and would extend the war to maybe 45 possibly 46 if Hitler did not get so paranoid and let his officers fight the war .
