George asked this question:

_So how does this coincide with Hasbro's Axis&Allies D-Day release? _

I believe they will both be released about the same time - in June to celebrate the 60th anniversary of the D-Day landing. I think the games will be quite different though. I was fortunate enough to playtest A&A D-Day (strategy articles available), and I think it is quite good. It is very similar to the large-scale A&A but simpler - smaller scale, no economy, and less playing time. But the basic ideas are similar (movement, combat system). And it is just D-Day.

Looking at Memoir 44, you will see a more generic game system with a variety of scenarios (ala Battle Cry). So you'll have less geographic detail, the scale will be smaller, but you'll get more flexibility.
