Ostheer will have different kind of vet so while both fractions tech up early in the game WH is left with better equipment but no vet.Also units like PzIII will apear much earlier than PzIV. They will be like Stubby PzIV or a Stug.The STG44 sniper will decrew heavy weapons quicker and probably will have more HP so he will be harder to counter than WH sniper.Elephant will probably have the longest gun range out of all super tanks.Finally its going to be fun, fun, fun!
There are some people like me who actually prefer the older stuff. Besides, the Eastern Front lasted much longer than the Western Front. Quite naturally, pre-'44 weapons make sense.
Panzer 3 is a disguise.Its really a tiger under a blanket
