The more that I think about the lack of a german campaign then the stranger it becomes - we all know that SS = $$ so a battle that features them but where you can't actually play them is a weird choice.
There again you could say the same about the original game - it features a battle that took place just a few miles down the road from the more famous one that the SS fought (although you do get the 'toys' - Tigers/Panthers - to play with in that).
From a sales perspective it's an odd decision.
From my point of view, both of the operations featured in Caen offer big challenges for the defender (historically at least) and would be very interesting to play.
