For the U.S. I assume it will be missing the M24 Chaffee, the M18 Hellcat, and probably the M26 Pershing. Maybe the recoilless rifles. These are my assumptions only. I don't know what parts of the German tin can armada would be missing as compared to NWE, nor am I speculating about other Allies.
Even if I'm correct, there is likely to be so much overlap that I doubt I'll miss any of the above. With the right map I can be happily in France 1944 just like with the right CM:BO maps I am happily in Italy in 1943.
Hell, as long as I'm happily not on the East Front somewhere, I'll be happily happy, happiness-wise.
